Two fractions are equivalent when they are both equal when written in lowest terms. The fraction 8 16 is equal to 1 2 when reduced to lowest terms. 3 6 is equivalent to 4 8 because 1 x 3 = 3 and 2 x 3 = 6; 4 8 is equivalent to 4 8 because 1 x 4 = 4 and 2 x 4 = 8; and so on. 3/4 - 3/8=6/8 - 3/8=3/8 PLEASE ANSWER. I NEED A EXPLANATION FOR ALL OF THEM. 1) 4x + 4 = 2x + 36 a) no solution b) x = 16 c) x = 20 d) infinitely many solutions. The mean, median, and mode are all equal for this set: (3,4,5,8,x). What's the value of 'x'? Statistics Organizing and Summarizing Data Simple Quantitative Displays.
This is a lesson for 3rd grade math about the concept of a fraction. Students color parts to illustrate fractions, write fractions from visual models and from number lines, and learn to draw pie models for some common fractions. Lastly they divide shapes into equal parts themselves and show the given fraction.
Fractions are formed when we have a WHOLE that is divided into so many EQUAL parts. | |||||

“three eighths” | The number ABOVE the line tells HOW MANY PARTS we have (the colored parts). The number BELOW the line tells how many EQUAL parts the whole is divided into. After halves, we use ordinal numbers to name the fractional parts (thirds, fourths, fifths, sixths, sevenths, and so on). |
1. Color the parts to illustratethe fraction.

How many parts is this “whole” divided into? Count. You should get 8 parts. Don't count the little lines. Count the “units” or the parts. One of them is like this: How many of them are colored?

How to draw pie models | ||||
Halves: split the circle with a straight line. | Thirds: draw lines at 12 o'clock, 4 o'clock, and 8 o'clock. | Fourths: First draw halves, then split those like a cross pattern. | ||
Fifths: Drawlike a man doing jumping jacks. |
