One-Step Division Equations - MathHelp.com - Math Help
By yourteachermathhelp
1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson students learn to solve one-step division equations. For example to solve x/4 = 2 multiply both sides of the equation by 4 to get x = 8. Next check the solution by substituting an 8 back into the original equation to get (8)/2 = 4 which is a true statement so the solution checks.

This lesson covers comparing fractions. Students learn to compare fractions with the same denominator, which are called like fractions, by comparing the numerators. For example, to compare 7/9 and 4/9, note that 7 is greater than 4, so 7/9 is greater than 4/9. Students also learn to compare fractions with the different denominators, which are called unlike fractions, by first finding a common denominator, then comparing the numerators. For example, to compare 1/2 and 1/3, first find a common denominator, or the Least Common Multiple of 2 and 3, which is 6. To get 6 in the denominator of 1/2, multiply the numerator and denominator by 3, to get 3/6. To get 6 in the denominator of 1/3, multiply the numerator and denominator by 2, to get 2/6. Next, compare 3/6 and 2/6. Note that 3 is greater than 2, so 3/6 is greater than 2/6, which means that 1/2 is greater than 1/3.

(Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 2) = (8 × 5) (8 × 2) = 40 16 = 56. (Distributive property.)Front Row is a free, adaptive, Common Core aligned math program for teachers and students in kindergarten through eighth grade. Front Row allows students to practice math at their own pace - learning advanced concepts when they 're ready and receiving remediation when they struggle. Front Row provides teachers with access to a detailed data dashboard and weekly email reports that show which standards are causing students difficulty, what small groups can be formed for interventions, and how their students are progressing in math.Discover more Common Core Math at https://www.frontrowed.com
