Answer 1

Answer:

Step-by-step explanation:

15) 1/5 X 7/8 + 9/15 X 7/8 =

Using Distributive property over Addition = 7/8 (1/5+9/15)

=> 7/8 (3/15 + 9/15)         ( LCM of 5 qand 15 is 15)

=> 7/8 (12/15)

=> 72/120

=> 7/10                 ( Simplified answer)

16) 6 rational numbers between -3/4 and -5/6 =

So, take -3/4 as -63/84  and  -5/6 as -70/84    

( As 84 is a common multiple of 4 and 6)

So,  -64/84 , -65/84 , -66/84 , -67/84 , -68/84 , -69/84 are the 6 numbers.

Answer 2

Given :  (1/5) * ( 7/8)  + (9/15) * (7/ 8)

To Find : Use distributive property to simplify

Solution:

(1/5) * ( 7/8)  + (9/15) * (7/ 8)

Taking (7/8) common

= ( 1/5  + 9/15)  (7/8)

= ( 1/5  + 3/5) (7/8)

= (4/5) (7/8)

= 7 /10

= 0.7

-3/4  and - 5/6

- 18/24  and   - 20/24

-180/240  and  - 210/240

Rational numbers in between

-181/240 , -183/240 ,  -187/240 ,-189/240 ,   -191/240 , -193/240
