Question 1.
Eric mows 4 lawns each week. Peter mows 3 times as many lawns as Eric. How many lawns does Peter mow each week?
3 × 4 = 12 lawns
Peter gets paid 8 dollars per lawn. How much does Peter earn each week?
_____________________
Answer:
Number of lawns Peter mows each week = 12.
Number of dollars Peter gets paid per week = 96.
Explanation:
Number of lawns Eric mows each week = 4.
Peter mows 3 times as many lawns as Eric.
=> Number of lawns Peter mows each week = 3 × Number of lawns Eric mows each week
= 3 × 4
= 12.
Number of dollars Peter gets paid per lawn = 8.
Number of dollars Peter gets paid per week = Number of lawns Peter mows each week × Number of dollars Peter gets paid per lawn
= 12 × 8
= 96.
Question 2.
Mrs. Kumar puts one vase on each of 6 tables. There are 5 flowers in each vase. How many flowers does she use?
______________________
19 of the flowers are yellow. The rest are white. How many flowers are white?
________________________
Answer:
Number of flowers she uses = 30.
Number of flowers are white = 11.
Explanation:
Number of tables on Mrs. Kumar puts one vase = 6.
Number of flowers in each vase = 5.
Number of flowers she uses = 6 × Number of flowers in each vase
= 6 × 5
= 30.
Number of flowers are yellow = 19.
Number of flowers are white = Number of flowers she uses – Number of flowers are yellow
= 30 – 19
= 11.
