Best ResponseYou've already chosen the best response.0We have this ratio \[\Large \frac{1}{4} \ \text{bedroom} \ : \ \frac{3}{7} \ \text{hour}\] Multiply both parts by 4 to turn the "1/4" into "4/4" which is just 1 \[\Large {\color{red}{4*}}\frac{1}{4} \ \text{bedroom} \ : \ {\color{red}{4*}}\frac{3}{7} \ \text{hour}\] \[\Large \frac{4}{4} \ \text{bedroom} \ : \ \frac{12}{7} \ \text{hour}\] \[\Large 1 \ \text{bedroom} \ : \ \frac{12}{7} \ \text{hour}\]

Best ResponseYou've already chosen the best response.0Did you use the formula \[\Large \frac{\text{Approximate Value}  \text{Actual Value}}{ \text{Actual Value}}\times 100\%\] they show it on the page

Best ResponseYou've already chosen the best response.0They also posted this How to Calculate Here is the way to calculate a percentage error: Step 1: Calculate the error (subtract one value form the other) ignore any minus sign. Step 2: Divide the error by the exact value (we get a decimal number) Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign)
