Answer:
3/20
Step-by-step explanation:
There are 60 children in a club. In the club, the ratio of the number of girls to the number of boys is 3:1
Step 1
We find the number of girls and boys
The ratio is given as:
Girls : Boys
3:1
The sum of Proportion = 3 + 1 = 4
The number of girls
= 3/4 × 60 children
= 45 girls
The Number of boys
= 1/4 × 60 children
= 15 boys
Step 2
From the question, we are told:
3/5 of the girls play a musical instrument.
The number of girls that play Instruments is calculated as:
3/5 × Number of girls
= 3/5 × 45 girls
= 27 girls
4/5 of the boys play a musical
instrument.
The number of boys that play Instruments is calculated as:
4/5 × Number of boys
= 4/5 × 15 boys
= 12 boys
Step 3
The fraction of the 60 children that play a musical instrument is calculated as:
Sum of boys and girls that play a musical instrument/ 60 children
= 27 girls + 12 boys/60
= 39/60
= 3/20
The fraction of the 60 children that play a musical instrument is 3/20

two times the sum of a number and 18 is at least -21
Answer:
2x + 18 ≥ 21
x ≥ 2/3
Step-by-step explanation:
Let sum be X
2 times the sum means 2x
the sum of a number and 18 means x + 18
at least -21 means ≥ 21
put them together, and you get, 2x + 18 ≥ 21
If solving for x,
2x + 18 ≥ 21
2x ≥ 3
x ≥ 2/3

5y−2x=10
8x+5y=60
Answer:
pick the simplest of the 2 equations
Step-by-step explanation:
5y-2x=10
5y = 2x +10
y = 2/5x + 2
now substitute
8x + 5(2/5X +2)=60
8x + 2x + 10 = 60
10x = 50
x = 5

What is another way to write 15 divided by 2?
15
O 15+2
O 15 x 2
Answer: [tex]15\times\frac{1}{2}[/tex]
Explanation:
Multiplying by 1/2 is the same as dividing by 2.
For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]
The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]
work out: 0.03 x 0.6
0.03 x 0.6
= (3 x 6) / 1000
= 18 / 1000
0.018
