a sixth grade class has 12 boys and 24 girls consider this statement: for every two boys there are 4 girls do you ag

Nitella [24]

So the ratio of boys to girls is 12:24.. now, is that an equivalent ratio as 2 boys for 4 girls? or 2:4? let's see.

$\bf \cfrac{boys}{girls}\qquad 12:24\qquad \cfrac{12}{24}\implies \boxed{\cfrac{1}{2}}
\\\\\\
\cfrac{boys}{girls}\qquad 2:4\qquad \cfrac{2}{4}\implies \boxed{\cfrac{1}{2}}$

you could start simplifying the 12/24 fraction by dividing by some common multiple, say 2, and get 6/12, then divide by 3 and get 2/4 and stop there.

then you'll notice that 12/24 is really 2/4 in disguise.

Share 800 in the ratio 9:7.

bulgar [2K]

Answer:

The numerator '9's share is 450 and the denominator '7's share is 350.

Step-by-step explanation:

Step-1: Add the ratios:

9 + 7
16

Step-2: Divide 800 by the sum of the ratios:

800 ÷ 16
=> 50

Step-3: Multiply 50 with each ratio:

9 x 50 = 450
7 x 50 = 350

Hence, the numerator '9's share is 450 and the denominator '7's share is 350.

Hoped this helped.

Angles A = 60, B = 2x, C = 3x and D = 25 are 4 angles on a straight, what 3 points is the value of angle B?*

iragen [17]

Answer:

B = 38°

Step-by-step explanation:

A straight angle is 180°. If your four angles total a straight angle, then ...

60 +2x +3x +25 = 180

95 = 5x . . . . . . subtract 85

x = 19 . . . . . . divide by 5

2x = 38 . . . . . angle B is 38°
