6 3/5 - 4 3/4?

This is pretty simple. First, you want to make the denominators the same, to make things easier. So find the LCM (Least Common Multiple), which is 20 in this case, and then multiply the 5 by 4 (to get 20) and vice versa for 4. Dont forget to multiply the numerator the same way. Now you should get something easier:

6 12/20 -4 15/20.

Now in this case, you must borrow a whole to finish this problem. So borrow a whole number from 6, (making it a 5) and bring it to the first fraction of the equation.

5 32/20 - 4 15/20.

Now, just solve. You should get 1 17/20. This cannot be simplified.

If 6/10 is multiplied by a fraction less than 1,which of these would be an answer 6/10,1/2,3/2,or 5

Pavlova-9 [17]

If $\frac{6}{10}$ is multiplied with a fraction less than 1, out of the given options $\frac{1}{2}$ would be the answer.

Explanation:

First, we need to determine what a fraction lesser than 1 is. If the numerator is lesser than the denominator, the fraction will be lesser than 1 whereas if the denominator is higher than the numerator is would equal more than 1.
If $\frac{6}{10}$ is multiplied with 1, we get the value $\frac{6}{10}$ . Since the fraction must be lesser than 1, $\frac{6}{10}$ cannot be an answer. So option 1 cannot be the answer.
The value of $\frac{6}{10}$ is 0.6. If it is multiplied with any value lesser than 1, the resulting value cannot be higher than the value of 0.6. The value of the fraction $\frac{3}{2}$ is 1.5 and the value of 5 are both greater than 0.6. So the third and fourth options cannot be the answer. So $\frac{1}{2}$ is the answer.

24 is 16% of what number

Eva8 [605]

Is/of = %/100 plug the numbers in 24/x = 16/100 then cross multiply then you get 2400 = 16x so you get x by itself so you would have to divide by 16. 2400/16 = 16x/16 the 16 on the x side cancel out so you get x = 150 (I used proportions)
