Answer:
24
Step-by-step explanation:
Step 1: We make the assumption that 120 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that $100\%=120$.
Step 4: In the same vein, $x\%=28.8$.
Step 5: This gives us a pair of simple equations:
$100\%=120(1)$.
$x\%=28.8(2)$.
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{120}{28.8}$
To calculate the square root, you can either use the √symbol on a calculator or you can manually find it using Prime Factorization. For non-perfect squares, Prime Factorization is the way to go.
The first two steps work for solving large perfect squares as well.
1. Divide your number into perfect square factors.
2. Take the square roots of your perfect square factors.
3. If your number doesn't factor perfectly, reduce your answer to simplest terms.
4. If needed, estimate. In some cases if you have memorized some of the square roots, you can estimate where the number would be.
ie.

you know that

and

, so you can estimate that the

would be between 7 and 8 but closer to 8.
5. <span>Alternatively, reduce your number to its lowest common factors as your first step.</span><span> Finding perfect square factors isn't necessary if you can easily determine a number's prime factors (factors that are also prime numbers).

Answer 200 to 520 and 300 to 580.
Step-by-step explanation:
Each one increases by 60.
1/16 cup..........................1 tablespoon
1 1/2= 3/2 cups................x tablespoons
1/16*x=3/2
x= 3/2 : 1/16=3/2*16= 24 tablespoons he needs
