16/21 divided by 4/9
leonid [27]
16/21 divided by 4/9 is equivalent to 16/21 x 9/4 = 144/84 which reduces to 12/7. So 12/7 is your answer.

Balu had a collection of coins. 1/2 of the coins are from asian countries, 1/3 of them from european countries, 36 are from amer
Georgia [21]

The total number of coins Balu had in his collection was <u>216 coins</u>, computed using the linear equation in one variable, <u>x = x/2 + x/3 + 36</u>.

Asian coins were 1/2 a fraction of this, that is, (1/2)*216 = <u>108 coins</u>.

We assume the total coins with Balu to be x.

The fraction of coins from Asian countries = 1/2.

Thus, the number of coins from the Asian countries = 1/2 of x = x/2.

The fraction of coins from European countries = 1/3.

Thus, the number of coins from the European countries = 1/3 of x = x/3.

The number of coins from America = 36.

Thus, the total number of coins = x/2 + x/3 + 36.

But, we assumed that the total number of coins is x.

Thus, we get a linear equation in one variable as follows:

x = x/2 + x/3 + 36.

We solve this equation as follows:

x = x/2 + x/3 + 36,

or, x - x/2 - x/3 = 36,

or, (6x - 3x - 2x)/6 = 36,

or, x/6 = 36,

or, x = 36*6 = 216.

Thus, the total number of coins Balu had in his collection was <u>216 coins</u>, computed using the linear equation in one variable, <u>x = x/2 + x/3 + 36</u>.

Asian coins were 1/2 a fraction of this, that is, (1/2)*216 = <u>108 coins</u>.

Which equation shows 2.4 as the constant of proportionality?
Nata [24]
I think it's c because if its proportional it should also be linear and c is the only linear equation
