In a fish tank, 1/5 of the fish are guppies and 1/12 of the fish are goldfish. Which equation most closely estimates the fraction of the fish that are guppies or goldfish in the tank. suggested answers: 1/2+1/2=1 , 1/2+1/4=3/4 , 1/4+1/4=1/2, 1/4+0= 1/4

Step-by-step explanation:

A or B = A+B

Given: In a fish tank, of the fish are guppies and of the fish are goldfish.

Then,  the fraction of the fish that are guppies or goldfish in the tank=

Hence, the equation most closely estimates the fraction of the fish that are guppies or goldfish in the tank:

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
