Answer: 6
Step-by-step explanation: By checking the factors of both numbers, you see that 6 is their greatest common factor.
30: 1, 2, 3, 5, 6, 10, 15, 30
42: 1, 2, 3, 6, 7, 14, 21, 42
Hope this helps!
Given : Two numbers 30 & 42 is given to us .
To Find : The HCF of 30 & 42 .
Solution : HCF is the highest number which divides the given two or more numbers without leaving any remainder .
So , let's find HCF ( Highest common factor ) by Division method :
= 30 ) 42 ( 1
- 30
__________
12 ) 30 ( 2
- 24
___________
6 ) 12 ( 2
- 12
0 .
The last divisor is 6 .
<u>Hence </u><u>the</u><u> </u><u>HCF</u><u> </u><u>is</u><u> </u><u>6</u><u>.</u>

Answer: 14
Fraction that choose hip hop= 1/3
Fraction that choose rap = 1/5
Fraction that choose rock will be:
= 1 - (1/3 + 1/5)
= 1 - (5/15 + 3/15)
= 1 - 8/15
= 7/15
Number of students that choose rock will be:
= 7/15 × 30
= 7 × 2
= 14 students
We then multi
a). (20 x 80) + (20 x 6) + (7 x 80) + (7 x 6)
