Smotret Domashnie Zadanie Po Matematike Upr 778 Vilenkin 6 Klass -

form a proportion, we check if the product of the extreme terms equals the product of the mean terms (the "cross-product" rule). : Mean terms : Calculation: , the first proportion is correct . 2. Check the second proportion For the second part of the exercise, we check the ratios 4.23.54.2 over 3.5 end-fraction 6.35.256.3 over 5.25 end-fraction using the same property. Extreme terms : Mean terms : Calculation: , the second proportion is also correct . Final Answer

The solution to exercise 778 in the 6th-grade mathematics textbook by Vilenkin depends on determining whether the given ratios form a valid proportion. To determine if the ratios 152.715 over 2.7 end-fraction 10.181 over 0.18 end-fraction form a proportion, we check if the product

Both given proportions are valid because the product of their extreme terms is equal to the product of their mean terms. You can find more practice problems and step-by-step guides on platforms like Skysmart GDZ . Check the second proportion For the second part
