# PLEASE HELP ME!For exercises 2-5, what is the best estimate for each product or quotient? Use compatible numbers.8.3 x 4.9 =12.1 x 2.95 =60.94 ÷ 5.7 =32.79 ÷ 3.1 =

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
