Answer:
The answer to your question is 7 large and 16 small
Step-by-step explanation:
Data
cost large frame = $13
cost small frame = $5
total number of frames = 23
total cost = $171
large frame = l
small frame = s
Process
- Write equations that help to solve the problem
l + s = 23 Equation l
13l + 5s = 171 Equation ll
-Multiply equation l by -5
-5l - 5s = -115
13l + 5s = 171
8l + 0 = 56
8l = 56
l = 56/8
l = 7
-Find s
7 + s = 23
s = 23 - 7
s = 16
-Conclusion
She bought 7 large frames and 16 small frames.

When we are looking at rounding, we round to the number that our fraction or decimal is located. So, since we are rounding to the nearest whole number, given our original mixed number (
) our answer will be either 7 or 8.
We can change
to a decimal to equal 7.8 by multiplying both our denominator and our numerator by 2 since 5 * 2 =10, which would change our fraction to
which is the same thing as .8
If we look at 7.8 and want to know if it is closer to 8 or 7, we just remember that when rounding, if it is 5 or above, you round up, anything else, you leave the number in front of it like it is. .8 is above 5 so we round 7 to the whole number 8. So, our answer is 8
