Answer 1

Answer:

CH - 8

1. 25% of 500 kg

= 25/100 x 500 kg

= 1/4 x 500 kg

= 1/1 x 125 kg

- 125 kg (answer)

2. 10% of 1 hour

= 10/100 x 60

= 1/10 x 60

= 1/1 x 6

= 6 minutes (answer)

3. Cost of 1 basket = 125/5

                               = 25

Cost of 12 such baskets = 25 x 12

                                        = 300 (answer)

4. 100/40 X 250

= 10/4 x 250

= 2500/4

=  625 (answer)

Answer 2

Answer:

Ch - 8

1. 25% of 500 = 25/100 × 500 = 125
2. 10% of 1 hour ( 60 min ) = 6
3. so find 1 basket cost that is 125/5 = 25 : 12 basket cost = 12× 25 = 300
4. 40% = 250 so 80% = 500 and 20 % = 40%/2 = 125 so 100 % is 250+250+125 = 625

Ch -9

1. six rational no. between -4/5 and -7/8 . first take lcm of denominator that is 40 so -32/40 and -35/40 both × 10 that is -320/400 and -350/400 six rational no. are -321/400,-322/400,323/400,324/400,325/400,326/400
2. 84/21 = 4/1 = 4
3. 45/13 × -65/9 = -25
4. -6/11 - 4/5 = -30/55 - 44/55 = -74/55
5. 21/24 ÷ 7/12 = 21/24× 12/7 = 3/2
