Accepted Solution

A:

Answer:(a) 8.3 x 4.9 = 40(b) 12.1 x 2.95 = 36(c) 60.94 ÷ 5.7 = 10(d) 32.79 ÷ 3.1 = 11Step-by-step explanation:Here, the given expressions are:(a) 8.3 x 4.9 Now, here 8.3 can be approximated as 84.9 can be approximated as 5.0So, 8.3 x 4.9 ≈ 8 x 5 = 40Hence, the suitable estimated product for 8.3 x 4.9 = 40(b) 12.1 x 2.95 Now, here 12.1 can be approximated as 12.2.95 can be approximated as 3.0So, 12.1 x 2.95 ≈ 12 x 3 = 36Hence, the suitable estimated product for 12.1 x 2.95 = 36(c) 60.94 ÷ 5.7
Now, here 60.94 can be approximated as 61.5.7 can be approximated as 6So, 60.94 ÷ 5.7 ≈ 61 ÷ 6 = 10 . 16Hence, the suitable estimated quotient for 60.94 ÷ 5.7 = 10(d) 32.79 ÷ 3.1
Now, here 32.79 can be approximated as 33.3.1 can be approximated as 3.So, 32.79 ÷ 3.1 ≈ 33 ÷ 3 = 11Hence, the suitable estimated quotient for 32.79 ÷ 3.1 = 11
