Question

Marla did 64 sit-ups each day for one week. Use the distributive property to sow an expression you ca. Use to find the total number of sit-ups Marla did during the week.

Answer 1

Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448

Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448

Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448

Explanation:

Marla did 64 sit ups each day for one week = 64 *7 = 448

A distributive property allows us to multiply a sum by multiplying each addend separately first and then summing the products together.

64 sit ups could be written as 60+4, 50+14 or 40+24.

Apply the distributive property:

Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448

Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448

Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448

We can try any two numbers whose sum is 64 and all will give us the answer 448....
