The proportion equal to a/b = c/d is A.) A/C = B/D

We will know if a proportion is equivalent when its cross products are equal.

a/b = c/d where ad = bc

since ad = bc, a/c = b/d

Carly placed 50 marbles in a bag. Fifteen of the marbles are pink, 8 marbles are black,
yuradex [85]

When you go into this problem, you want to figure out your marble ammount to 50 so in this case we will say C for color and 50 for the total ammount of marbles.

We know 15 are pink, 8 are black, 2 are green, 18 are clear, and 7 are striped

15P/50

8B/50

2G/50

18C/50

7S/50 for a total of 50 marbles

Now we use the chart to decide our awnsers  

A. We know our propability of drawing a green and clear is 20/50 which if we simplify is a 2/5 ratio. If We put this in perspective 2/5 is rare and is unlikley to even.

B. We know a striped marble is 18/50 or 1.8/5 ratio which is mainly unlikely

C. We have 23/50 marbles that are black and pink, our propability is about 2.3/5 and gives us an even chance to get one of these

D. We know we have 33/50 marbles that are pink and clear and gives us a 3.3/5 chance of getting one of  these and gives us an even to likely chance of getting one of these.

E. If we have a total of 17 marbles in these 3 colors, we have a 1.7/5 chance of getting one of these and is probably impossible to unlikey.

A rectangle has a height of 3 cm and width of 5cm. A proportional rectangle has a height of 12cm. What would be the width?
Schach [20]

The ratio will be same

  • Let width be x

\\ \sf\longmapsto \dfrac{3}{5}=\dfrac{12}{x}

\\ \sf\longmapsto 3x=5(12)

\\ \sf\longmapsto 3x=60

\\ \sf\longmapsto x=\dfrac{60}{3}

\\ \sf\longmapsto x=20cm
