What is (4/9-7/15) divided by 13/10

1 answer:

6 0

First find least common denominator to subtract.
9=(3)×3
15=(3)×5
3×3×5=45 is lcd
4/9=20/45
7/15=21/45
(20/45-21/45)=(20-21)/45=-1/45
-1/45÷13/10
multiply by reciprocal instead of dividing
-1/45×10/13=(1×10)/(45×13)

-10/585

7. Five swimmers entered a competition. Four of the swimmers had their turns. Their scores are 9.8, 9.75, 9.79 and 9.81 seconds

arsen [322]

Answer:

We must order these decimals from least to greatest. Then we must determine how the least compares with the winning score.

9.80 -> 3

9.75 -> 1

9.79 -> 2

9.81 -> 4

The least decimal is 9.75. Now we must determine how 9.75 compare with the winning score.

The last swimmer must get a score less than 9.75 seconds in order to win.
