Answer 1

Q 1:-

3/15 ÷ 18/30

a = 3/ 15 and b = 18/30

a ÷ b = a × 1/b

3/15 × 1/18/30

get reciprocal

3/15× 30/18

by solving we get the answer is 1/3

Q 2:-

-10/4 ÷ -45/21

a = -10/4 and b = -45/21

a ÷ b = a × 1/b

-10/4 × 1/-45/21

( - × - = +)

get reciprocal

-10/4 × -21/45

by solving we get the answer is 7/3

Q 3:-

-16 ÷ -8/19

a = -16 and b = -8/19

a ÷ b = a × 1/b

-16 × 1/-8/19

get reciprocal

-16 × 19/-8

by solving we get the answer 38

Q 4:-

-90/88 ÷ 30

a = -90/88 and b = 30

a ÷ b = a × 1/b

get reciprocal

-90/88 × 1/30

by solving we get the answer is -3/88

Q 5:-

-45/216 ÷ -6/15

a = -46/216 and b = -6/15

a ÷ b = a × 1/b

-45/216 × 1/-6/15

get reciprocal

-45/216 × -15/6

by solving we get the answer is 675/1296

Hope that it's help to you

Answer 2

1) 3/15 ÷ 18/30

= 3/15 x 30/18

= 2//9

2)-10/4 x 21/-45

= -2 x 21 / 4 x -9

= -42 / -36

= -21 / -18

= -7 / -6

3) -16 ÷ -8/19

= -16 x 19/-8

= -2 x 19

= -38

4) -90/88 ÷ 30

= -90/88 x 1/30

= -3 /88

5) -45/216 ÷ -6/-15

= -45/216 x -15/-6

= -675/ - 1296
