2 4/7 times 1/4 plz help i need help but m extremely stupid plz help

Answers

9/14 because u do 2 times 7 to get 14 and then add 4 and then multiply straight across

It is 9/14

*Turn 2 4/7 into an improper fraction by doing denominator x whole number x numerator, so 7 x 2 + 4.
* 2 4/7 turns into 18/7 and now you do 18/7 x 1/4 by doing numerator x numerator and denominator x denominator.
*The answer is 18/28 and when simplified it is 9/14 because I divided the numerator and denominator by 2.

Apples are on sale at the grocery store at a price of 8 apples for $4.00 .Mark buys 12 apples. If he is charged the sale price for apples, how much will Mark pay?

Answers

You can do this problem 2 ways. Whichever works easier for you:

Take the cost of 8 apples and divide it by 8 in order to find a per apple cost
4/8 = $.50 per apple
Then multiply the total number of apples by the cost per apple
12 * $.50 = $6.00 paid

Or

You can divide the total number of apples by 8 to find how many units of apples you have

12/8 = 1.5

Then multiply the number of units by the cost for 1 unit (8 apples)

1.5*$4 = $6.00

Can you guys help me with fractions I forgot over the summer. Please explain easily.

So in order to add the fractions together you need to first find a common denominator. For the very first problem you can use 63 as a denominator because 7*9=63. Now for the numerator. So you have 4/7 and 8/9. We just multiplied 7 by 9 so now we need to do that for 4 also. 4*9=36. Now we have 36/63. For 8/9 we multiply 8 by 7 to get 56. Now we have 36/63 + 56/63. Once you add those together you simplify your answer.
