Question

28 1/20 - (7 - 2 8/15) =

Answer 1

28 1/20 - (7 - 2 8/15) =28 1/20 - 7 + 2 8/15=560/20-7+38/15=(1680-420+152)/60=1412/60
23 32/60=23 8/15

Answer 2

28 + 1/20 - (7 + 28/15)

First, we need to convert 28 and 1/20 to a common denominator: 28 = 560/20 1/20 = 1/20

Now, we can subtract the second term from the first: 560/20 + 1/20 - (7 + 28/15)

Combine the first two terms: 561/20 - (7 + 28/15)

Now, we need to find a common denominator for the remaining terms: 561/20 - (7*15/15 + 28/15) 561/20 - (105/15 + 28/15)

Combine the terms inside the parentheses: 561/20 - 133/15

To subtract these fractions, we need to find a common denominator, which is 60: (561*3)/(20*3) - (133*4)/(15*4) 1683/60 - 532/60

Now, subtract the fractions: 1151/60

So, 28 + 1/20 - (7 + 28/15) = 1151/60
