I can see you come from outside the USA. No insults intended!!
.

Or even better...

A!!
PROPORTION!!
.
So... Let's say 7 is proportional to 48... so 7/5 = 48/x, where x is the number equivalent to ratio of 5.

Cross multiply!!

Divide 7 on both sides.

x = 34 2/7.

What is the value of the expression when t is equal to 15? 2t divide 3
goblinko [34]
If we take the value of t to be 15 and then we perform the calculations of 2 times t divided by 3, we can express it all by two equations substituting the value given for t like so:
t = 15
2t/3 = 2(15)/3 = 30/3 = 10
