Question

please give me answer ​

Answer 1

1] 3×1000/20 = 150g

2] (17/3) - (7/6) = 34-7/6 = 27/6 = 9/2

3] 7.20 × 1000 = 7200g { ∵ 1kg = 1000g }

4] denote the box by a

=> 3/7 = x/35 => x = 35×3/7 = 15

5] 1/5 ÷3 = (1/5)× (1/3) = 1/15

Answer 2

Answer:

1) 3/20 of 1kg

= 3/20 × 1000g

= 3 × 50

= 150g

so, (1) - (b)

2) 5whole2/3 - 1whole1/6

= 17/3 - 7/6

= 34/6 - 7/6

= 27/6

= 9/2

so, (2) - (e)

3) 7.20 kg

= 720/100 × 1000g

= 7200g

so, (3) - (d)

4) 3/7 = x/35

or, x = 3/7 × 35

or, x = 3×5

or, x = 15

so, (4) - (a)

5)1/5÷3

= 1/5×1/3

= 1/15

so, (5) - (c)
