I think the answer is A because it I'm right it did double the size.
the volume of the box is L x W x H so it should be 7x5x4=140
(179.3)/(61.5) *10 time both sides by 10 to get rid of the decimal
1793/615
615*2= 1230 615 goes two times into 1793 before exceeding
1793-1230=563 remainder which is less than 615 hence will give a decimal when divided by 615
563/615= 0.9
2+0.9 = 2.9 is the answer
for a longer decimal you can easily use a calculator
4/5 + 8/9. First we have to find a common denominator for

and

.

Now we are going to add:

Make

a mixed number:

So the answer is
3.65 is less than 
First, you must change the mixed number into a decimal so you can compare the two numbers.

Then, you must compare the terms.
3.65 < 3.75
3.65 is less than
