Question

В швейной мастерской было 14 кусков ткани,по 30 м в каждом,и 6 кусков,по 40 м в каждом.На пошив изделий израсходовали 280 м 45 см матери.Сколько метров ткани осталось?

Answer 1

1) 14 · 30 = 420 (м)
2) 6 · 40 = 240 (м)
3) 420 + 240 = 660 (м) - всего ткани
4) 660 м - 280 м 45 см = 659 м 100 см - 280 м 45 см = 379 м 55 см

Answer 2

1)14*30=420(м)-в 14 кусках
2)6*40=240(м)-в 6 кусках
3)420+240=660(м)-было всего 
660м=66000см и 280м45см=28045см
4)66000-28045=37955(см)=379м55см

Answer 3

Calculation of Remaining Fabric in the Sewing Workshop

To calculate the amount of fabric remaining in the sewing workshop, we need to subtract the fabric used for making the garments from the total fabric available.

Given information: - There were 14 pieces of fabric, each measuring 30 meters. - There were 6 pieces of fabric, each measuring 40 meters. - The total fabric used for making the garments was 280 meters and 45 centimeters.

Let's calculate the total fabric available: - 14 pieces of fabric, each measuring 30 meters: 14 * 30 = 420 meters - 6 pieces of fabric, each measuring 40 meters: 6 * 40 = 240 meters - Total fabric available: 420 meters + 240 meters = 660 meters

Now, let's calculate the fabric remaining: - Total fabric available: 660 meters - Fabric used for making the garments: 280 meters and 45 centimeters, which is equivalent to 280.45 meters - Fabric remaining: Total fabric available - Fabric used = 660 meters - 280.45 meters = 379.55 meters

Therefore, there are approximately 379.55 meters of fabric remaining in the sewing workshop.

Please note that the above calculation assumes that all the fabric pieces were used entirely and there was no wastage or leftover fabric from the garments made.
