Question

One week.

2. Marla did 65 sit-up
Which expression can you use to find the
total number of sit-ups Marla did during the
week?
A (7 x 6) + (7 x 5)
(B) (5 x 60) + (5 X 7)
(7+60) x (7 + 5)
D(7 x 60) + (7 X 5)

Answer 1

(7 × 60) + (7 × 5) (option d)

Explanation:

No. of sit ups = 65

No. of days in 1 week = 7

So,

Expression for total no. of sit ups during the week

= 7 × 65

= 7 × (60 + 5)

By following distributive property where we distribute the value based on the number of terms inside the parentheses with the multiplicative factor,

= (7 × 60) + (7 × 5) (option d)

=》Final answer will be 455.
