Mr. Schaum used 10 buckets to collect rainfall. someone look at the pic and helpp

(1.25•4)+(1.625•2)+(2.375•2)+(2.125+0.625)

Step-by-step explanation:

First you need to discern the values of each of the markers, as the number line is divided into 8ths between every whole number it’s safe to assume that the decimals 0.125, 0.25, 0.375, 0.5, 0625, 0.75, and 0.875 are going to be used here.

This gives us the all of the possible values for the amount of rain:

0.625 Gallons (Marked once)

1.25 Gallons (Marked 4 times)

1.625 Gallons (Marked twice)

2.125 Gallons (Marked once)

2.375 Gallons (Marked twice)

Next you need to multiply every amount by the number of marks it has on the graph.

Ex.: 1.25 times 4, because there are 4 marks above that value, meaning 4 buckets

have 1.25 gallons of rain in them. On the other hand, any value marked only once

doesn’t need to be multiplied by one, as any number times 1 is itself.

Finally, you add all of your multiplication problems together, and should have an equation like this. (Please note the parentheses are for readability, and you would get the same answer without them due to PEMDAS.)

(1.25•4)+(1.625•2)+(2.375•2)+(2.125+0.625)

so, converting firstly the mixed fractions to improper fractions and then "adding".
