Answer 1

Hey payal!

So here is the answer of your questions!

-------

Q.1. Estimate the product by rounding off both the factors ,also find the actual product of 15*48

Answer =>

15 ⟶ 20
48 ⟶ 50
20 × 50 = 1000
The estimated product is 1000

》 15 × 48 = 720

The actual product is 720

Q.2. Write the range of product and then find the actual product of 14×53

Answer =>

The lower bound is 10 × 50
The upper bound is 20 × 60
The range estimate of 14 × 53 is estimated as follows -:
10 × 50 ≤ 15 × 53 ≤ 20 × 60
500 ≤ 15 × 53 ≤ 1200

Therefore, the range based estimate of the product is 500 ≤ 15 × 53 ≤ 1200

》 14 × 53 = 742

The actual product is 742
