How many 3/8s does it take to make 3/2?

We need 4  3/8's

Step-by-step explanation:

How many 3/8 does it take to make 3/2

3/8 * x = 3/2

Divide each side by 3/8

x = 3/2 ÷ 3/8

Copy dot flip

x = 3/2* 8/3

x = 3/3 *8/2

x =4

We need 4  3/8's

It would take 4 s to make

Step-by-step explanation:

To find how many 3/8s it takes to make 3/2, we just have to divide

Because, we just need to know how many times we need to divide until get .

So, the division would be

it would take 4 s to make

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)
