3/10+(-1/3)
subtract.
10. 14 - (-8)
13. 2/3-3/2

See below in bold.

Step-by-step explanation:

3/10 + (-1/3)

= 3/10 - 1/3

Convert the fractions to denominator 30:

= 9/30 -10/30

= -1/30.

10. 14 - (-8)

= 14 + 8

= 22.

13. 2/3 - 3/2

The least common denominator is 6 so we have:

= 4/6 - 9/6

= - 5/6.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
