7t=35
t=5
Answer:
It is.
Step-by-step explanation:
1.5cm is in the plan.
1.92m is in real life.
We need to convert m to cm so 1.92m=192cm
The ratio is 1:128.
1.5cm in plan as is 192 cm in real life.We write that as the ratio of: 1.5 : 192.
We need to prove that it is the actual scale so we equal this ratio(1.5:192) and the other ratio(1:128):
1.5 : 192 = 1 : 128
Then we multiply the numbers that are in and out of the equation like this:
1.5 * 128 = 192 * 1
192 = 192 It is proven beacuse the numbers are equal. The scale of the house is 1:128

It is the biggest number that two numbers are divisible by.
For example, if you did 12 and 24
The factors of 12 are:
1, 2, 3, 4, 6, 12
The factors of 24 are:
1, 2, 3, 4, 6, 8, 12, and 24
Their greatest common factor would be 12 since, it is the greatest number that each number can be divisible by.
