Answer:
1.5 as decimal, 1 1/2 as a fraction
Step-by-step explanation:
1. convert 2 5/6 & (-1 4/12) to a improper fraction.
17/6 and -16/12
2. multiply 17/6 by 2 to match -16/12's denominator
17/6 * 2 = 34/12
We now have
34/12 + -16/12
A positive number plus a negative number is the same thing as subtraction so we remove the negative sign and replace the plus with a minus sign.
We have:
Now solve. 34-16 = 18
our answer is 18/12
Fractions, you can covert it to a decimal by dividing the numerator to the denominator.
Decimals, you can convert it to a fraction by reducing it.
they are both equally related because you can convert each other. Same with multiplying and dividing.

Answer:
7d +d +d=45
Step-by-step explanation:
The length shown for the green line is shown as 45 therefore the black line also has 45
to prove your answer:
7d + d + d = 45
9d = 45
you need to get the letter d on its own so you
9d ÷9 = 45 ÷ 9 (what you do on the one side,you do on the other)
d = 5
*substitute
5 + 7(5) + 5
= 5+ 35 + 5
= 40 +5
= 45
