First is 7 second is 8 third is 3
Answer:
7/165
Step-by-step explanation:
This is a mixed recurring decimal (the zero is not repeating)
We take number after the decimal point 042
then we subtract the non repeating.In this case is 0 so we not subtract anything
This will be the numerator 42
Now ,the denominator:
For each repeating decimal we write a 9 (in this case 2 nines)
For each non repeating decimal we write a zero
Denominator is 990
42/990 = 7/165
7:165 = 0.0424242......
Are these three different questions? if so:
1: add 19 to both sides to get a = 3 +19
answer: a = 22
2: multiply both sides by 7 to get y = 10 * 7
answer: y = 70
3: divide both sides by 5 to get g = 100/5
answer: g = 20
hope this helped! good luck :)
