Why does: 5/3 x 18 = 30?

Try writing it out as 5/3 * 18/1 (all whole numbers are over 1). So you can multiply the numbers straight across if you write the fractions horizontally… so…

5 x 18 = 90

3 x 1 = 3

So then you end up with 90/3 as a fraction and that can be Reduced because 90 divided by 3 is….. 30! Does that help

5

— * 18 = 30

3

step 1:

3*6 =18

step2:

cut out 3 and write 1 instead.cut out 18 and write 6.

step 3 :

so now we have 5*6 which is 30.

alternate method:

5 * 18 = 90

3 * 1 = 3

so then it is 90/3

which is 30

let us try out another example:

2

— * 16

4

step 1:

firstly u must answer this question.4* __ =16

that question must always be asked.

here the answer is 4

step 2:

then u must cut off 4 and write 1 and cut off 16 and write 4

step 3:

so now since we have 2/1 * 4

the answer will be 8.

alternate method:

2 * 16 = 32

4 * 1 = 4

so then 32/4

which is 8.

there……….wasnt that easy?

18 can be translated into 18/1. you multiply the top numbers so 5 x 18 which equals 90. you then multiply the bottom numbers or 3 x 1 equals 3. 90/3 equals 30.

18 divided by 1 is 18 so another way to write 18 is 18/1.

5*18=90 while 3*1= 3.

5/3* 18/1 = 90/3

90 divided by 3 is 30.

5/3 = 1 2/3

1X 18=18

2/3 or 0.666 x 18 = 11.988

18 + 11.988= 29.988

round it up to a whole number = 30

Five-thirds is like three-thirds (a whole one) plus two-thirds more. If you take three-thirds of 18, that’s one whole 18=18. To get two-thirds more, figure out one-third of 18=6. Two thirds of 18=12.

The whole 18 plus two-thirds more is 18+12=30.
