A) $644
b) 50%
work:
1,299 - 655 = 644
1st change 1 5/6 into a mixed number:
1 5/6 = 11/6
New problem:
8/10 divided by 11/6
to divide fractions you turn the 1st fraction upside down and then change the division sign to a multiplication sign:
8/10 / 11/6
10/8 * 11/6
=55/24 or 1 7/24
number one is 280 because 4/2 is 2 + 2 is 4 then you multiply 7 and that is 28 ^ 2 which is 280
