Question

Three-fourths of a number plus two-fifths of the number is 13 less
than one-half of the number. Find the number.​

Answer 1

Step-by-step explanation:

Let the number be'a'

(3a/4)+(2a/5) = (3a/2)-13

(3a/4)+(2a/5)-(3a/2) = -13

(15a+8a-30a)/20 = -13

(8a-15a)= (-13)(20)

-7a = -260

a=(260/7)

a=37.1428
