4. A 16-piece orchestra wants to choose one
pishuonlain [190]

Answer:

1/12

Step-by-step explanation:

subtract the four soloists who can't be chosen from the total musicians

16-4=12

Itzhak is one person out of 12 who could be chosen to speak

Also the question is annoying because nobody calls an orchestra with 16 people a "16 piece orchestra"

Writing equivalent ratios and ordered pairs Gallons 1 2 3 Quarts 4 8 12 which ordered pairs represents the equivalent ratios in
Sphinxa [80]

Step-by-step explanation:

gallons to quarts have the ratio 1:4.

there are 4 quarts in a gallon (hence the name of quarts by the way).

so, the question is really, which order pair have also a 1:4 ratio between x and y ?

(1, 4)

(2, 8)

(3, 12)

the (4, 1) would represent a 4:1 ratio.

and as you know, 4/1 is different to 1/4.

a ratio is nothing else than a fraction. just the "whole" is different.

the pure fraction 1/4 means that the whole is 4/4, has 4 times 1/4.

a ratio 1:4 (you can also write as 1/4) means that the whole has 5 (1+4) parts.

other than that they are compared and calculated with the same way as normal fractions.
