How do u do 2 over 3 =A over 60 PLZ NO LINKS THANKS

Ivanshal [37]

Hey there!

2/3 = a/30

First: you have to CROSS MULTIPLY the given numbers

2(30) = 3(a)

2(30) = 60

3(a) = 3a

New EQUATION: 3a = 60

Second: DIVIDE 3 to BOTH SIDES

3a/3 = 60/3

CANCEL out: 3/3 because that gives you 1

KEEP: 60/3 because that helps you solve for your a-value

60/3 = a

60/3 = 20

Therefore, your answer is: a = 20

Good luck on your assignment and enjoy your day!

i need help with my math :( im horrable with it i cant do divideing fractions nor multiply and i dont know most of my multiples

vladimir1956 [14]

Step-by-step explanation:

To multiply the fractions, like

$\frac{1}{4} \times \frac{1}{9}$

Multiply the top,

then multiply the bottom.

$\frac{1}{4} \times \frac{1}{9} = \frac{1 \times 1}{4 \times 9} = \frac{1}{36}$

Try to use a calculator if you aren't arithmetic heavy, but I suggest you to try to remember them because they are going to be helpful for courses like Algebra, Calculus, Statistics, etc.

To divide fractions, like

$\frac{ \frac{1}{5} }{ \frac{1}{8} }$

You take the top number,

$\frac{1}{5}$

Then you flip the bottom number,

$\frac{8}{1}$

Then multiply the two

$\frac{1}{5} \times \frac{8}{1} = \frac{8}{5}$

And that is your answer. Comment if you need more clarification
