Question

1. 55.9 x 1.4
2. 51.1 x 0.45

Explanation:

Step1: Calculate 55.9×1.4

First, multiply 559×14 = 7826. Then, since there are a total of 1 + 1 = 2 decimal places in the factors, we place the decimal point 2 places from the right in the product. So, 55.9×1.4 = 78.26.

Step2: Calculate 51.1×0.45

First, multiply 511×45 = 23005. Then, since there are 1 + 2 = 3 decimal places in the factors, we place the decimal point 3 places from the right in the product. So, 51.1×0.45 = 22.995.

Answer:

1. 78.26
2. 22.995
