To solve this, set up two equations using the information you're given. Let's call our two numbers a and b:
1) D<span>ifference of two numbers is 90
a - b (difference of two numbers) = 90
2) The quotient of these two numbers is 10
a/b (quotient of the two numbers) = 10
Now you can solve for the two numbers.
1) Solve the second equation for one of the variables. Let's solve for a:
a/b = 10
a = 10b
2) Plug a =10b into the first equation and solve for the value of b:
a - b = 90
10b - b = 90
9b = 90
b = 10
3) Using b = 10, plug it back into one of the equations to find the value of a. I'll plug it back into the first equation:
a - b = 90
a - 10 = 90
a = 100

Answer: The numbers are 100 and 10</span>
Move the decimal so that there is one whole number.
0.00000482 => 4.82
We moved 6 units to the left so:
4.82 * 10^-6

I'll think bout it.
I may join, but I won't be on that much.
-- The smallest 6-digit whole number is 100,000 .
-- The largest 4-digit whole number is 9,999 .
-- The difference is (100,000 - 9,999) = 90,001 .
Answer:
the answer is 672
Step-by-step explanation:
420 × 60% = 252
420 + 252=672
625 is the total number of learners
