how do i figure out : 56 is 70% of ?
54% of what number is 152?
and 25 is 62 1/2 of?
70% = 0.7
0.7x = 56
x = 56/0.7
x = 80
Do the others the same way.
ohh this makes so much sense!! thank you!
You're very welcome.
To figure out these questions, we need to use the concept of percentages and solve for the unknown quantities. Let's break down each question step by step:
1. "56 is 70% of what number?"
To find the number, we divide 56 by 0.70 (which is the decimal equivalent of 70%). The formula to find the whole number when we know the percentage is: Whole number = (Part / Percentage). In this case, it would be: Whole number = (56 / 0.70). Simply divide 56 by 0.70 to get the answer: 80.
2. "54% of what number is 152?"
Similarly, to find the number, we divide 152 by 0.54 (which is the decimal equivalent of 54%). Applying the formula Whole number = (Part / Percentage), it would be: Whole number = (152 / 0.54). Divide 152 by 0.54 to get the answer: 281.48 (rounded to two decimal places).
3. "25 is 62 1/2% of what number?"
First, we need to convert 62 1/2% to decimal. Divide 62.5 by 100 to get 0.625. Then, we divide 25 by 0.625 to find the whole number. Using the formula Whole number = (Part / Percentage), it would be: Whole number = (25 / 0.625). Divide 25 by 0.625 to get the answer: 40.
So, the answers to the questions are:
- 56 is 70% of 80.
- 54% of 281.48 is 152.
- 25 is 62 1/2% of 40.
