Solve for k
3/k = 4/5

k = 3.75 or 3 3/4

Step-by-step explanation:

=

This can be solved using cross multiplication. Multiply 3 by 5 and then 4 by the variable k.

3 x 5 = 15

4 x k = 4k

Both of these numbers (15 and 4k) can be set up into an equation.

4k = 15

4k/4 = 15/4

k = 3.75 or 3 3/4

k = 3.75

Step-by-step explanation:

Solve for k,

3/k = 4/5

Cross multiply:

4 x k = 3 x 5

4k= 15

Divide both sides by 4 to get the value of k

K= 15/4

K= 3.75

I hope this helps.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
