Question

Compute without using the calculator: 1.25×14.9+0.75×1.1+14.9×0.75+1.1×1.25

Answer 1

32

Explanation:

There are two ways to do this.

First Method:

Isolate 1.25 and 0.75:
1.25(14.9 + 1.1) + 0.75(14.9 + 1.1)

Then you factor:

(1.25 + 0.75)(14.9 + 1.1)

After that, you just add and multiply.

(2)(16) = 2 x 16 = 32

32 is your final answer.

Second Method:

Isolate 14.9 and 1.1:
14.9(1.25 + 0.75) + 1.1(1.25 + 0.75)

Then you factor:

(14.9 + 1.1)(1.25 + 0.75)

After that, you just add and multiply.

(16)(2) = 16 x 2 = 32

32 is your final answer.

Both explanations are pretty much related, you just factor different numbers to start off.

Answer 2

the answer is 32 have a great day
