Description
"Adding and Subtracting Fractions with Different Denominators" Fraction Addition and Subtraction PPT Courseware 2
Mingqiao Primary School has a rectangular experimental field, in which ( ) is planted with cucumbers and ( ) with tomatoes.
1. What fraction of the land is occupied by cucumbers and tomatoes?
2. How much larger is the area for cucumbers than for tomatoes?
3. How much smaller is the area for growing tomatoes than the area for growing cucumbers?
When calculating the addition of fractions with different denominators, you can first convert the fractions with different denominators into fractions with the same denominator, and then calculate according to the calculation rules for fractions with the same denominator. The calculation result can generally be reduced to the simplest fraction.
Summary of this lesson
Fractions with the same unit can be added directly, but fractions with different units cannot be added directly, so they must be converted into fractions with the same unit first, that is, they must be divided first and then added. What are we learning in this lesson? Can you tell other students about your experience and experience in adding and subtracting fractions with different denominators?
