Answer:

This shows us that there are 1400 readers.

Step-by-step explanation:

To work this out you would first need to find how many times 5% goes into 100%, You can do this by dividing 100 by 5, this gives you 20. This is because the whole amount is equivalent to 100%.

To work out the total number of readers you would multiply 70 by 20, this gives you 1400. This is because we know that 70 is equivalent to 5% and that 5% goes into 100% 20. So by multiplying 70 by 20 we are working out the total (100%), and that this shows us there are 1400 readers.

1) Divide 100 by 5.

$100/5=20$

2) Multiply 70 by 20.

$70*20=1400$

Answer:

(a) O+ to A+

$O+:A+=90:45$

$O+:A+=18:9$

$O+:A+=2:1$

(b) AB- : AB+

$AB-:AB+ = 6:4$

$AB-:AB+ = 3:2$

$AB-:AB+ = 12:8$

(c): B+ to total

$B+ : Total = 20 : 195$

$B+ : Total = 4 : 39$

$B+ : Total = 40 : 390$

Step-by-step explanation:

Given

$A+ = 45$ $B+ = 20$ $AB+ =6$ $O+=90$

$A-=21$ $B-=0$ $AB-=4$ $O-=9$

$Total = 195$

Solving (a): O+ to A+

We have:

$A+ = 45$

$O+=90$

So, the ratio is:

$O+:A+=90:45$ ---- first comparison

Divide by 5

$O+:A+=90/5:45/5$

$O+:A+=18:9$ ---- Second comparison

Divide by 45

$O+:A+=90/45:45/45$

$O+:A+=2:1$ ---- Third comparison

Solving (b): AB- to AB+

We have:

$AB+ =6$

$AB-=4$

So, the ratio is:

$AB-:AB+ = 6:4$ ---- first comparison

Divide by 2

$AB-:AB+ = 6/2:4/2$

$AB-:AB+ = 3:2$ ---- Second comparison

Multiply by 2

$AB-:AB+ = 6*2:4*2$

$AB-:AB+ = 12:8$ ---- Third comparison

Solving (c): B+ to total

We have:

$B+ = 20$

$Total = 195$

So, the ratio is:

$B+ : Total = 20 : 195$ ---- first comparison

Divide by 5

$B+ : Total = 20/5 : 195/5$

$B+ : Total = 4 : 39$ ---- Second comparison

Multiply by 2

$B+ : Total = 20*2 : 195*2$

$B+ : Total = 40 : 390$ ---- Third comparison

Please help me! I have no idea how to do this

elena-s [515]

The best way to do this is to make up values for the sides.

Say the lengths of square B's sides are each 4 cm. That means A's sides are 2 cm.

So, the area of square B is 4^2 = 16 cm^2, and A's area is 4 cm^2. We can see the shaded area is half of A, so it's 2 cm^2.

What percent of 16 is 2?

2 / 16 * 100 = 12.5%
