Answer: 49 students
Step-by-step explanation:
2 /7 of students in a school wore shorts today. The number of students to be selected in order to get 14 students who will wear shorts to school will be:
Let the number of students that will be sampled be y. This will be:
2/7 of y = 14
2/7 × y = 14
2y/7 = 14
Cross Multiply
2y = 7 × 14
2y = 98
y = 98/2
y = 49
49 students will be selected randomly.
Answer:
Lets use the distributive property and to this...
Fist 8×53 might be hard so lets break it to (50×8)+(3×8)
⇒400+24
⇒424
And we still have the 125 whcih we have to multiply with 424
Here again we do it the same way but its more packed with steps.
424×125
⇒[(400×100+400×25)+(20×100+20×25)+(4×100+4×25)]
⇒[(40000+10000)+(2000+500)+(400+100)]
⇒[(50000)+(2500)+(500)]
⇒50000+2500+500
⇒50000+3000
⇒53000
