Math:

Equivalent in math means equal in value or amount. Two main areas that we use equivalent is when referring to fractions or referring to ratios.

At times, on the PATs, you will not be able to find your answer as one of the choices but an equivalent fraction or ratios might be given.

Examples:
2/3 is equivalent to 4/6, 6/9, 20/30, 66/99, and many others
15/20 is equivalent to 3/4, 6/8, 9/12, 12/16 75/100 and many others

2:5 is equivalent to 4:10, 6:15, 20:50, 40:100 and many others
8:10 is equivalent to 4:5, 16:20, 80:100 and many others

Science: 

There are 2 types of moon eclipses. They are the lunar eclipse and the solar eclipse.

Lunar eclipse - an eclipse in which the moon appears darkened as it passes into the earth's shadow. The Sun, Earth, and Moon need to be lined up exactly and the Earth needs to be in the middle. The sun’s rays are blocked from reflecting off the moon. The moon appears orange or reddish during a lunar eclipse. This can only happen during a full moon.

Solar eclipse - an eclipse in which the sun is blocked by the moon. The Earth, Moon and Sun must be lined up exactly and the moon needs to be in the middle. The moon appears dark with a bright ring around the outer edge. This can only happen during a new moon.
