Question

Rosa finds the product of 32 and 96. she rewrites 96 as a sum or difference of two numbers and uses the distributive property. which of the following could be a step in her computations?
a. 32×95+31
b. 30×98
c. 2700+12
d. 3200-128

Answer 1

Solution:

We are given with the  two numbers=32 and 96

Product of the given numbers=$32*96= 3072$

But Rosa rewrites the 96 as a sum or difference of two numbers and uses the distributive property

As we know, the Distributive property is $a(b+c)= ab+ac$

Now,  $32*96 = 32*(100-4) = 3200-128$

So, option 'd' is correct
