Multiplication is a shorthand way of writing repeated addition. 3 + 3 + 3 + 3 = 4 x 3.
The denominator shows the total number of equal parts in the whole. The numerator shows how many of those equal parts we have or are talking about. In the fraction [ggfrac]2/3[/ggfrac] the 3 shows there are 3 equal parts, and this fraction represents 2 of the 3 equal parts.
[ggfrac]1/5[/ggfrac] + [ggfrac]1/5[/ggfrac] + [ggfrac]1/5[/ggfrac] = [ggfrac]3/5[/ggfrac]. I added the numerators and kept the same denominator, 5.
[ggfrac]1/3[/ggfrac] + [ggfrac]1/3[/ggfrac] + [ggfrac]1/3[/ggfrac] + [ggfrac]1/3[/ggfrac] + [ggfrac]1/3[/ggfrac] = [ggfrac]5/3[/ggfrac]. I added the numerators and kept the same denominator.
[ggfrac]2/5[/ggfrac] + [ggfrac]2/5[/ggfrac] + [ggfrac]2/5[/ggfrac] + [ggfrac]2/5[/ggfrac] = [ggfrac]8/5[/ggfrac]. [ggfrac]5/5[/ggfrac] is equal to 1. [ggfrac]8/5[/ggfrac] has three more fifths than [ggfrac]5/5[/ggfrac] so [ggfrac]8/5[/ggfrac] is greater than 1.
5 x [ggfrac]3/4[/ggfrac]
Yes it would be the same. Sample answer: I would multiply 20 x [ggfrac]2/9[/ggfrac] because I think it would take less time than adding.
Gita is wrong. She multiplied both the numerator and the denominator of the fraction by 4. She should have just multiplied the numerator by 4 and kept the denominator the same.
Husam is wrong. 6 x [ggfrac]1/3[/ggfrac] is [ggfrac]6/3[/ggfrac] or 2 and 2 is not less than 1.
Sample answer: 2; 9; 10
A fraction represents a part of a whole.
The denominator of a fraction is the number below the line. The denominator shows the total number of equal parts in the whole.
The numerator of a fraction is the number above the line. The numerator shows how many equal parts of the whole the fraction represents.
A fraction where the numerator is 1.
A fraction greater than 1 is a fraction where the numerator is greater than the denominator. A fraction greater than 1 represents an amount greater than one whole.
A mixed number is a number that includes both a whole number and a fraction.
The whole is 1 of something such as 1 circle or 1 unit on a number line.
Equal parts are parts of the same size that the whole is divided into.
Write [ggfrac]1/4[/ggfrac] + [ggfrac]1/4[/ggfrac] + [ggfrac]1/4[/ggfrac] as a multiplication problem and give the answer.
Camila multiplied 3 x [ggfrac]1/4[/ggfrac] and got [ggfrac]3/12[/ggfrac]. Explain what she did wrong.
Write a short word problem where you would solve 7 x [ggfrac]1/2[/ggfrac]. Give the answer.
"My students loved the videos. I started the video subscription in May and used them as a review before the state test, which I know contributed to 100% of my class passing the state test."
