Hope i helped!
estimates:
a) 9000
b)25
c)4500
figure out how I arrived at those. Estimates are ball park math, you do it in your head to no more than two digits.
To solve these multiplication problems, you need to multiply the given numbers together. Let's break it down step by step:
1. 31.04 × 300:
To multiply decimals, ignore the decimal points at first. Multiply 3104 (31.04 without the decimal point) by 300:
3104 × 300 = 931,200
Since the original question involves decimals, we need to consider the decimal places. The given number, 31.04, has two decimal places, and we need to move the decimal point two places to the right in the final answer:
931,200.00
So, 31.04 × 300 = 931,200.00
2. 0.56 × 48:
Multiply 56 (ignoring the decimal point) by 48:
56 × 48 = 2,688
Considering the original decimal places, there are two decimal places in the question; therefore, we need to move the decimal point two places to the left:
26.88
So, 0.56 × 48 = 26.88
3. 47.2 × 93:
Multiply 472 (ignoring the decimal point) by 93:
472 × 93 = 43,896
Considering the original decimal places, there is one decimal place in the question; therefore, we need to move the decimal point one place to the left:
4,389.6
So, 47.2 × 93 = 4,389.6
I hope this explanation helps you understand how to solve these multiplication problems.
