10.
7 / 21 = 7 • 1 / 7 • 3 = 1 / 3 = 0.3333...
Multiply and divide 0.3333... by 100.
100 • 0.3333... / 100 =
33.3333... / 100 = 33.3333... %
11.
6.35 / 77 = 0.0824675325
Multiply and divide 0.0824675325 by 100.
100 • 0.0824675325 / 100 =
8.24675325 / 100 = 8.24675325 %
8.25 % rounded on two decimal places.
6.35% = 0.0635
so,
0.0635 * 77 = 4.89
I can help you with both questions. Let's start with question 10.
To find what percent of 21 is 7, we can use the formula: (part/whole) * 100.
In this case, the part is 7 and the whole is 21. So, the formula becomes: (7/21) * 100.
To calculate this, divide 7 by 21: 7 ÷ 21 = 0.333.
Then, multiply the result by 100 to convert it to a percentage: 0.333 * 100 = 33.3%.
Therefore, 7 is approximately 33.3% of 21.
Now, let's move on to question 11.
To calculate the sales tax, we need to find 6.35% of $77.00.
To do this, we can multiply the price ($77.00) by the sales tax rate (6.35%) expressed as a decimal (0.0635).
Mathematically, it looks like this: $77.00 * 0.0635 = $4.8895.
Rounding this to two decimal places, we get $4.89.
Therefore, Julie will pay $4.89 in sales tax.
I hope that helps! Let me know if you have any further questions.
