81/5 + 4 2/5 i need to know cus i dont understand it

63/5 or 12 (3/5)

Step-by-step explanation:

It is 8 whole (1 ÷ 5) plus 4 whole (2 ÷ 5)

So,we can write it as 8 (1/5) + 4 (2/5)

Then we will take those mixed fractions to improper fractions by using the rule of multiplication.

8 will be multiplied by 5 and then the value will be added to 1. Same rule will be applied for the second fraction.

(41÷5) + (22÷5)

Now we will take L.C.M. (Least common multiple) for both denominators 5 and 5. The L.C.M of 5 and 5 = 5

(41 + 22)/5

= 63/5

It is the answer. Also we can make this improper fraction into mixed fraction by dividing the whole number by 5.

12 (3/5)

46.2+112.3

step-by-step explanation:

yes. we do proportions in probabilities.
