7% x 5%
To write 35% as the sum of two benchmark percents, we need to identify two benchmark percents that add up to 35%. Benchmark percents are common percentages that are easy to work with. The most common benchmark percents are 10%, 25%, 50%, and 75%.
One way to write 35% as the sum of two benchmark percents is to break it down as 25% + 10%. Another way is to break it down as 10% + 25%.
Now let's see how we arrived at these sums:
Method 1:
To find 25% of a number, you can divide the number by 4. So, 25% of a number is the same as dividing the number by 4.
To find 10% of a number, you can divide the number by 10. So, 10% of a number is the same as dividing the number by 10.
Method 2:
To find 10% of a number, you can divide the number by 10, as mentioned earlier.
To find 25% of a number, you can divide the number by 4. So, 25% of a number is four times greater than 10% of the same number.
Now let's look at writing 35% as a multiple of a percent.
To write 35% as a multiple of a percent, we need to find a percent that divides evenly into 35%. One such percent is 5%.
To find 5% of a number, you can divide the number by 20. So, 35% is the same as 7 times 5%.
To summarize:
35% can be written as 25% + 10%
35% can also be written as 10% + 25%
35% can be written as 7 * 5%
