Answer: 11/2 x 15/4 = 165
/8 = 205
/8 = 20.625
Step-by-step explanation:
Multiple: 11
/2 * 15
/4 = 11 · 15 2 · 4 = 165
/8
Multiply both numerators and denominators.
Answer:
5,000
Step-by-step explanation:
When a number is 5 or above, you would round up. When it is below 4 or below, you round down.
Since 5,182 the 1 is below 1, 5 would remain the same.
9514 1404 393
Answer:
18
Step-by-step explanation:
90 = 18·5
126 = 18·7
180 = 18·10
990 = 18·55
The greatest common factor of these numbers is 18.

<em>Comment on the GCF</em>
It can be useful to know Euclid's algorithm for finding the GCF:
- Determine the remainder from dividing the larger number by the smaller.
- If the remainder is zero, the smaller number is the GCF. If the remainder is non-zero, use it to replace the larger number and repeat from step 1.
For example, 126 mod 90 = 36; 90 mod 36 = 18; 36 mod 18 = 0, so 18 is the GCF of 126 and 90. (The modulo function 'mod' returns the remainder from division.)

Step-by-step explanation:
Answer:
1. 0.472
2. 0.25
Step-by-step explanation:
1. reduce the fraction with 3 = 1\4 + 2\9
write all numerators above the Least common denominator 36 =9 + 8\36
Add numbers = 17\36 and the alternate form is 0.472
2. Divide the numerator and denominator by three = 3 ÷ 3\12 ÷ 3 = 0.25
I can't do the others now I have an exam(sorry)
