Answer 1

Step-by-step explanation:

1 = 33/200 into decimal

to get 200 as 1000, we will multiply 200 by 5, to get 1000, so we will multiply 33 as well, we will get 165/1000, the decimal will be, 0.165.

2a) = m×n - 2

2b) = y + p/q

3 = 2.5 kg = 2500 g

so, 2500g/500g = 25/5 = 5/1 ( In ratio, we don't put units like kg, l, m etc. ) so the ratio is 5:1.

4a) = 28.5 cm

4b) = 40.005 kg

5 = Sum of ratios = 2+3 = 5

Ravi's part of money = 2/5×750 = 2×150= 300 rupees

Anuj's part of money = 3/5×750 = 3×150= 450 rupees

Hope it helps you..
