Answer:
The greatest common factor is 1.
Step-by-step explanation:
In this question we will factorize the expressions given and select the common factors among all.
For 9x² = 1×3×3×X×X
For 2 = 1×2
For 6x = 1×2×3×X
So we find the common factor in all expressions is = 1
Answer is 1.
Don't know how to type the symbole infront of the 50 so I will subsitute
£50=$50
so 1:4
add it up
1+4=5
so 5 total units
$50=5 units
divide by 5
$10=1 unit
so 1:4=10:10 times 4=10:40
the answer is 10:40
