Answer:

add the subtrahend to the difference

Step-by-step explanation:

The usual way to check a subtraction problem is to add the subtrahend to the difference to see if you get the minuend as a result.

Paloma can add 5/8 to her result to see if she gets 1 3/4.

She can also perform the subtraction using decimal fractions to see if she gets the same result.

1.750 -0.625 = 1.125

How do I solve part b and c

OLEGan [10]

Answer:

part a: 52%

part b: 0.4

part c: 0.24

Step-by-step explanation:

For part one, you find the frequency of the number of people that are less that 20. You add the number of tics in each bar and you divide by the total.

so for part a it is (7+6+9+4)/ (7+6+9+4+4+12+8)

for part b you add up the values that are greater than 25(less than 35)

(12+8)/total

part c you find the number of people between 25 and 30

that's 12

over total

12/total
