Question

в литровой банке помещается 910 г пшена или 780 г гороха какая масса? а? 3 банок пшена или 4 банок гороха?б)7банок пшена или 8 банок гороха

Answer 1

3 банок пшена=910*3=2730(г) 4 банок гороха=780*4=3120(г) 7 банок пшена=910*7=6370(г) 8 банок гороха=3120*2=6240(г)

Answer 2

Calculation of Mass in a Liter Jar

To calculate the mass of 910 g of wheat or 780 g of peas, we need to determine the mass of 1 jar of each type of grain.

According to the given information, a liter jar can hold either 910 g of wheat or 780 g of peas.

Therefore, the mass of 1 jar of wheat is 910 g, and the mass of 1 jar of peas is 780 g.

Number of Jars for a Given Mass

a) To find out how many jars are needed for 3 jars of wheat or 4 jars of peas, we can use the following calculations:

- For 3 jars of wheat: Multiply the mass of 1 jar of wheat (910 g) by 3. - 3 jars of wheat = 910 g * 3 = 2730 g

- For 4 jars of peas: Multiply the mass of 1 jar of peas (780 g) by 4. - 4 jars of peas = 780 g * 4 = 3120 g

Therefore, 3 jars of wheat have a mass of 2730 g, and 4 jars of peas have a mass of 3120 g.

b) For 7 jars of wheat or 8 jars of peas, we can use the same calculations:

- For 7 jars of wheat: Multiply the mass of 1 jar of wheat (910 g) by 7. - 7 jars of wheat = 910 g * 7 = 6370 g

- For 8 jars of peas: Multiply the mass of 1 jar of peas (780 g) by 8. - 8 jars of peas = 780 g * 8 = 6240 g

Therefore, 7 jars of wheat have a mass of 6370 g, and 8 jars of peas have a mass of 6240 g.

Please note that these calculations are based on the given information and assume that the mass of the grains remains constant.
