Answer 1

Answer:

first convert the mixed fraction into proper fractions by multiplying the denominator with the number and adding the numerator to it

(5*8+7/8)=47/8,(7*4+1/4)=29/4,(4*5+2/5)=22/5

now multiply the fractions to get a common denominator

in this case we are taking the common denominator to be 40

(47/8)*(5/5)=235/40,(29/4)*(10/10)=290/40,(22/5)*(8/8)=176/40

now solve the equation

235/40-290/40+176/40=121/40
