- [Division Property of Equality] Divide 5 on both sides:

So we are trying to find the numerator of 42 in relation of 6/7.
42 divided by 7= 6 So 6 x 6 from the numerator of 6/7 = 36.
So 6/7 written as a fraction with a denominator of 42 is 36/42.
Answer:
3/4
Step-by-step explanation:
To answer this question we must first calculate the area of GHJK:
- A= GH*HJ
- A= (LM/2)* (MN/2)
- A= LM*MN/4
- LM/MN is the area of LMNO
- So the area of LMNO is 4 times the area of GHJK
- A is the area of LMNO and S the area of GHJK
- S= A/4
- A-S= A-A/4 = 3A/4
- so the area that is not shaded is 3/4
Answer:
1.1) Rational
1.2) Rational
1.3) Irrational
1.4) Rational
1.5) Rational
1.6) Irrational
Step-by-step explanation:
Rational means it can be represented as a fraction where the numerator and denominator are whole numbers and vice versa for irrationals.
