McGraw-Hill Math Grade 3 Answer Key Chapter 7 Lesson 8 Problem Solving
Answer the hidden question. Then solve the problem.
A butterfly traveled 248 miles in three days. It flew 67 miles on Monday and 83 miles on Tuesday. How many miles did the butterfly travel on Wednesday?
The butterfly flew 98 miles on Wednesday.
let m be the number of butterflies on Wednesday
(67 + 83) + m = 248
150 + m = 248
248 – 150 = 98
m = 98
There are 4 ants on a branch. There are 4 times as many ants on a rock. Half of the ants on the rock move onto a leaf. How many ants are on the leaf? Draw a picture to help you solve if you need to.
