Question

1− 7/15 3 5 3/8− 2 5/8

Answer 1

1-7/15=8/15

35 3/8-2 5/8= 32 6/8

Answer 2

To calculate the expression 1 - 7/15 - 3 5/8 - 2 5/8, you can follow these steps:

Step 1: Subtract 7/15 from 1: 1 - 7/15 = (15/15) - (7/15) = 8/15

Step 2: Convert the mixed numbers to improper fractions: 3 5/8 = (3 * 8 + 5) / 8 = 29/8 2 5/8 = (2 * 8 + 5) / 8 = 21/8

Step 3: Subtract the two improper fractions: (29/8) - (21/8) = (29 - 21) / 8 = 8/8 = 1

Step 4: Subtract the results from Step 1 and Step 3: (8/15) - 1

Now, to subtract these two fractions, you need to find a common denominator. The common denominator for 15 and 1 is 15. So, you need to rewrite 1 with a denominator of 15:

1 = 15/15

Now subtract:

(8/15) - (15/15) = (8 - 15) / 15 = (-7)/15

So, the final result is -7/15.
