6.Use a proportion to solve the problem
31% of 70
x/100 = 31/70; 43.66
x/71 = 31/100; 22.01
x/31 = 71/100; 0.22
71/x = 31/100; 229.03
I'm not too sure what the answer is here...
It's 22.01
Thank you. ^^
Are you still there? ^^; (not rushing you, just asking)
To solve the problem, we need to find 31% of 70 using a proportion. Let's go through the steps again:
Step 1: Set up the proportion. We want to find "x" which represents 31% of 70. So, we can set up the proportion as:
x/100 = 31/70.
Step 2: Cross-multiply and solve for "x". Cross-multiplying means multiplying the numerator of the left fraction (x) with the denominator of the right fraction (70), and multiplying the numerator of the right fraction (31) with the denominator of the left fraction (100).
70 * 31 = 100 * x
Step 3: Simplify the equation by performing the multiplication:
2170 = 100x
Step 4: Solve for "x" by dividing both sides of the equation by 100:
2170/100 = x
x = 21.7
Therefore, 31% of 70 is equal to 21.7.
