Question

If anyone Is nice enough to check my math (don’t judge the horrible handwriting..I don’t usually write like this)..I’d be thankful!

Answer 1

I’ll check it give me a minute I’m mainly writing this so I know to come to this just sec

Answer 2

The result is
`(27)/(2)`

Explanation:

We have to resolve:

`[(13)/(50) +((-11))/(70)]:[((-16))/(35) .(1)/((-60)) ]`

First we are going to analyze by separate:

`[(13)/(50) +((-11))/(70)]`

We have to look for the least common denominator between 50 and 70, which is 350, then we have to rewrite:

`[(13)/(50) +((-11))/(70)]=[(91)/(350)+ ((-55))/(350) ]\\\\=[(91-55)/(350) ]\\\\=[(36)/(350)]`

We can simplify dividing in 2:

`(36)/(350) =(18)/(175)`

Now we have to look the other part:

`[((-16))/(35) .(1)/((-60)) ]`

This is a multiplication so we have to cross-simplify:

We can't simplify 35 and 1 but we can simplify (-16) and (-60) in 4:

`[((-16))/(35) .(1)/((-60)) ]=[(4)/(35) .(1)/(15) ]\\\\=[(4)/(525)]`

Now uniting what we analyzed separately:

`(18)/(175):(4)/(525)`

We can simplify, we have a division then we have to simplify numerator with numerator and denominator with denominator.

We are going to simplify the numerators in 2 and the denominators in 175:

`(18)/(175):(4)/(525)=(9)/(1) :(2)/(3)=(27)/(2)`

Then the result is
`(27)/(2)`
