Question

Represent the following fractions as a decimal and percent: 7/20 and 5/9​

Answer 1

Answer: 7/20 = 0.35 or 35%. 5/9 = 0.55555.... or 55.5555....%

Step-by-step explanation: 7/20 is the same as 0.35 when you divide them: 20 goes into 7 zero times. Bring down a zero once you have 0. in the quotient place. 20 goes into 70 three times. 3 multiplied by 20 is 60. 70 minus 60 is 10. 20 goes into 10 zero times. Bring down another zero. 20 goes into 100 five times. So we now have 0.35. Move the decimal place two spaces to the right to get the percent: 35%.

The same goes for 5/9: 9 goes into 5 zero times. Place a decimal after 0 and bring down a zero. 9 goes into 50 five times. 9 times 5 is 45. 50 minus 45 is 5. We can see a pattern here, so we can assume the next number will also be 5. We now have 0.55555.... as a percent, move the decimal place two spaces to the right: 55.56% rounded.
