Question

Help this mom please! :) The sum 51 5/6 + (- 37 1/12), is equal to what? Thank u! :) Mom

Answer 1

\(\bf 51\cfrac{5}{6}+\left(-37\cfrac{1}{12}\right)\\ \quad \\ \quad \\

{\color{blue}{ 51\cfrac{5}{6}\implies \cfrac{51\cdot 6+5}{6}\implies \cfrac{311}{6}\\ \quad \\

-37\cfrac{1}{12}\implies \cfrac{-37\cdot 12+1}{12}\implies \cfrac{-443}{12}\\ \quad \\}}

51\cfrac{5}{6}+\left(-37\cfrac{1}{12}\right)\implies \cfrac{311}{6}+\left(\cfrac{-443}{12}\right)\implies \cfrac{311}{6}-\cfrac{443}{12}\\ \quad \\
\implies \cfrac{622+443}{12}\implies \cfrac{355}{4}\)

Answer 2

thats what i got, but thought it was wrong! thank so very much :)

Answer 9

\(\bf 51\cfrac{5}{6}+\left(-37\cfrac{1}{12}\right)\\ \quad \\ \quad \\

{\color{blue}{ 51\cfrac{5}{6}\implies \cfrac{51\cdot 6+5}{6}\implies \cfrac{311}{6}\\ \quad \\

-37\cfrac{1}{12}\implies \cfrac{-37\cdot 12+1}{12}\implies \cfrac{-443}{12}\\ \quad \\}}

51\cfrac{5}{6}+\left(-37\cfrac{1}{12}\right)\implies \cfrac{311}{6}+\left(\cfrac{-443}{12}\right)\implies \cfrac{311}{6}-\cfrac{443}{12}\\ \quad \\
\implies \cfrac{622-443}{12}\implies \cfrac{179}{12}\)

Answer 10

88 3/4, OR 88 11/12

Answer 11

i am confused

Answer 12

hmmm .... well, on the previous one... I did make a mistake... I use the +... I added the numerator, you do have a minus.... .so ... I sorta made a quick typo and added by mistake

Answer 13

I dont see any of the possible answers in your equations., or mine...

Answer 14

\(\bf \cfrac{a}{b}+\left(-\cfrac{c}{d}\right)\implies \cfrac{a}{b}-\cfrac{c}{d}\)

Answer 15

ol.... lemme recheck myself

Answer 16

hmm I see my another mistake.... gimme a sec

Answer 17

ok

Answer 18

\(\bf 51\cfrac{5}{6}+\left(-37\cfrac{1}{12}\right)\\ \quad \\ \quad \\

51\cfrac{5}{6}\implies \cfrac{51\cdot 6+5}{6}\implies {\color{blue}{ \cfrac{311}{6}}}\\ \quad \\

37\cfrac{1}{12}\implies \cfrac{37\cdot 12+1}{12}\implies {\color{blue}{ \cfrac{445}{12}}}\\ \quad \\

51\cfrac{5}{6}+\left(-37\cfrac{1}{12}\right)\implies \cfrac{311}{6}+\left(-\cfrac{445}{12}\right)\implies \cfrac{311}{6}-\cfrac{445}{12}\\ \quad \\
\implies \cfrac{622-445}{12}\implies \cfrac{177}{12}\)

Answer 19

but that answer is not one of the answers to pick from

Answer 20

i posted the 4 answers above

Answer 21

\(\bf \cfrac{177}{12}\implies {\color{red}{ 14\cfrac{3}{4}}}\implies \cfrac{14\cdot 4+3}{4}\)

Answer 22

thank u!!

Answer 23

well... ahemm I shoulld say... \(\bf \cfrac{177}{12}\implies \cfrac{59}{4}\implies {\color{red}{ 14\cfrac{3}{4}}}\implies \cfrac{14\cdot 4+3}{4}\)

Answer 24

it simplifies to to \(\bf \cfrac{59}{4}\) and you can write as a mixed fraction of \(\bf 14\cfrac{3}{4}\)
