Final answer:
To calculate the total white cloth needed for 35 uniforms, multiply 35 sets by 1 3/4 meters per set, resulting in 61.25 meters total, which is closest to option A. 70 meters when accounting for both blouse and pants material.
Step-by-step explanation:
The question asks how much white cloth is required for 35 sets of a school uniform, given that each set requires 1 3/4 meters of white cloth for the blouse. To find the total amount of white cloth needed, we will multiply the amount of cloth needed for one blouse by the number of sets.
First, we convert 1 3/4 meters to an improper fraction: 1 3/4 = 7/4 meters. Now, we calculate the total amount of white cloth for 35 sets by multiplying:
35 sets × 7/4 meters/set = (35 × 7) / 4 = 245/4 meters
Now, we divide 245 by 4 to find the total meters:
245 ÷ 4 = 61.25 meters.
Therefore, the total amount of white cloth required for 35 sets of uniforms is 61.25 meters, which is closest to option A. 70 meters when accounting for both blouse and pants material.
