10.Mr.Cartwright bought 2 7/8 pounds of grapes for his lunches. If he paid $1.79 for each pound about how much did he pay for the grapes?
A.6
B.3
C.7
D.4
I have to round the answer to something but how'd you get 2.875 Ms.Sue? What does 7/8 equal
change 7/8 to a decimal by dividing 8 into 7.000
divide that number into 1.79
oops!
I didn't see the 2 7/8
so after you divide 8 into 7.000, add the 2 to it.
My glass must need to be cleaned.
Multiply your answer after you divide i into 7.000 and add 2 to it by $1.79.
Sorry about the confusion.
To find out what 7/8 equals, you can divide 7 by 8.
To divide a whole number by a fraction, you can multiply the whole number by the reciprocal of the fraction. The reciprocal of 8/1 is 1/8.
So, to find 7/8, we can do:
7 ÷ 8 = 7 × (1/8) = 7/8
Therefore, 7/8 is equal to 0.875 in decimal form.
Now, let's calculate the total cost of the grapes:
Mr. Cartwright bought 2 7/8 pounds of grapes. We know that each pound cost $1.79.
To calculate the total cost, we need to multiply the weight of the grapes by the cost per pound.
Weight of grapes = 2 7/8 pounds = 2.875 pounds (as we found earlier)
Total cost = Weight of grapes × Cost per pound = 2.875 × $1.79
To calculate this, you can use a calculator:
Total cost ≈ $5.155
Since you need to round the answer, you can round it to the nearest cent:
Total cost ≈ $5.16
Therefore, Mr. Cartwright paid approximately $5.16 for the grapes.
So, the answer to the question would be A. $6 (rounded up) based on the given options.
