-5/8+(-8/5)= i do not understand how to solve this

first find a LCM or least common multiple

-25/40+(-64/40)=

add the numerators or top number

-88/40

then you simplify it

-2 8/40

-2 1/5

I hope this is good enough:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

the square root of what number? if you add that, then someone will probably answer the question.
