Question 3.
\(\frac{3}{6}\) + \(\frac{1}{6}\) = ___________
Answer:
\(\frac{3}{6}\) + \(\frac{1}{6}\)
The denominator of both the fraction is same.
We can add the numerator directly.
\(\frac{3}{6}\) + \(\frac{1}{6}\) = \(\frac{4}{6}\)
Question 4.
\(\frac{4}{10}\) + \(\frac{1}{10}\) = ____________
Answer:
\(\frac{4}{10}\) + \(\frac{1}{10}\)
The denominator of both the fraction is same.
We can add the numerator directly.
\(\frac{4}{10}\) + \(\frac{1}{10}\) = (4 + 1)/10 = \(\frac{5}{10}\)
Question 5.
\(\frac{7}{8}\) – \(\frac{3}{8}\) = _____________
Answer:
\(\frac{7}{8}\) – \(\frac{3}{8}\)
The denominator of both the fraction is same.
We can subtract the numerator directly.
\(\frac{7}{8}\) – \(\frac{3}{8}\) = (7 – 3)/8 = \(\frac{4}{8}\)
Question 6.
\(\frac{9}{12}\) – \(\frac{2}{12}\) = _____________
Answer:
Given the fractions,
\(\frac{9}{12}\) – \(\frac{2}{12}\)
The denominator of both the fraction is same.
We can subtract the numerator directly.
\(\frac{9}{12}\) – \(\frac{2}{12}\) = (9-2)/12 = \(\frac{7}{12}\)
Equivalent Fractions
Write an equivalent fractions.
Question 7.
\(\frac{3}{4}\) _________
Answer:
Equivalent fractions are fractions with different numbers representing the same part of a whole.
\(\frac{3}{4}\) × \(\frac{2}{2}\) = \(\frac{6}{8}\)
Question 8.
\(\frac{9}{15}\) __________
Answer:
Equivalent fractions are fractions with different numbers representing the same part of a whole.
\(\frac{9}{15}\) × \(\frac{2}{2}\) = \(\frac{18}{30}\)
Question 9.
\(\frac{24}{40}\) ____________
Answer:
Equivalent fractions are fractions with different numbers representing the same part of a whole.
\(\frac{24}{40}\) × \(\frac{2}{2}\) = \(\frac{48}{80}\)
Question 10.
\(\frac{5}{7}\) ____________
Answer:
Equivalent fractions are fractions with different numbers representing the same part of a whole.
\(\frac{5}{7}\) × \(\frac{2}{2}\) = \(\frac{10}{14}\)

Writing Now it’s your turn. Answer Problem 2. Then write about how you solved the problem, step by step.:
Problem 2.
The Perez family ordered a large pizza for dinner, A large pizza is divided into 8 slices. Marco ate \(\frac{3}{8}\) of the pizza. Ramon ate 1 slice more than Marco. Emilio ate the rest. How much of the pizza did Emilio eat?
A. \(\frac{1}{8}\) of the pizza
B. \(\frac{2}{8}\) of the pizza
C. \(\frac{4}{8}\) of the pizza
D. \(\frac{5}{8}\) of the pizza
Answer:
Given,
The Perez family ordered a large pizza for dinner, A large pizza is divided into 8 slices.
Marco ate \(\frac{3}{8}\) of the pizza.
Ramon ate 1 slice more than Marco. Emilio ate the rest.
\(\frac{3}{8}\) + \(\frac{1}{8}\) = \(\frac{4}{8}\)
\(\frac{4}{8}\) + \(\frac{4}{8}\) = 1
Thus the correct answer is option C.

Number/Symbol Cards: 2 sets labeled 1, 2, 3, 4, 6, 8
Number of Players 2
Set Up
Give each player 2 sets of number cards. Players shuffle their cards and place them face down in a stack.
How to Play
(1) One player shuffles arid deals all cards facedown. Players stack their cards.
(2) Players take 3 cards from the top of their stacks. Using 2 of the 3 cards, each player makes a fraction whose numerator is less than or equal to its denominator. The unused card is returned to the bottom of the player’s stack.
(3) Players compare the fractions. The player with the greater fraction earns 1 point. If the fractions are equivalent, each player earns 1 point.
(4) Repeat Steps 2 and 3. The player with more points after all the cards have been used is the winner.
