The factor is 8.
3 x 8 = 24
2, 6 3/7
3, 2 8/9
4, 15 1/4
5, 9 2/3
6, 7 5/8
Hi there! :D So you're wondering what's 6 3/4+3 5/6, right? Well first of all, we need to find a common denominator. In this case, we can use 12. (In case you don't know how to make common fractions, here's the steps:
1. Select your two numbers, 3/4 and 5/6. We multiply 4 x 6 = 24. That's the common denominator. But, we can reduce that to 12 by dividing by 2.
2. Multiply. 3/4 = 9/12. You must multiply by the same number. (3 x 3 = 9 and 4 x 3 = 12). Do that for 5/6 and you'll get 10/12.
Now we do 6 9/12 + 3 10/12. Add. 6 + 3 = 9 and 9/12 + 10/12 = 19/12 which equals 1 7/12 + 9 = 10 7/12.
10 7/12 is the answer you're looking for! Hope it helped! :D
Anzelm wants to burn 540 calories while jogging. Jogging burns about 12 calories per minute.
he usually plans to stop and rest for about 5 minutes.
m represents the total minutes.
12 calories per minute.
for m minutes the calories burn is 12m
He stop and rest for about 5 minutes. so we need to subtract 5 from total minutes
So expression becomes 12(m-5)
He wants to burn 540 calories. So we set the calories = 540
The equation becomes ,
12(m-5) = 540
Now we solve for m , total number of minutes
12(m-5) = 540(divide by 12 on both sides)
m - 5 = 45
m = 50 ( add 5 on both sides)
Anzelm should plan to be out jogging for 50 minutes
