Answer 2

To solve the expression:

-2 ÷ 5 - 1/3 - 7/10 ÷ 1_1/15, let's break it down step by step:

First, let's simplify the mixed numbers:

1_1/15 = 16/15

Now, let's calculate the division of fractions:

-2 ÷ 5 = -2/5

7/10 ÷ 16/15 = 7/10 * 15/16 = 105/160 = 21/32

Now, let's substitute the values back into the expression:

-2/5 - 1/3 - 21/32

To combine fractions, we need a common denominator:

The least common multiple of 5, 3, and 32 is 480.

Multiplying the fractions to have a common denominator:

(-2/5)(96/96) - (1/3)(160/160) - (21/32)(15/15) = -192/480 - 160/480 - 315/480

Now, we can combine the fractions:

= (-192 - 160 - 315)/480 = -667/480

Therefore, the simplified value of the expression -2 ÷ 5 - 1/3 - 7/10 ÷ 1_1/15 is -667/480.
