40 is what percent of 150
MariettaO [177]

Always use this formula to find a percentage:

<span>% / 100 = Part / Whole</span> replace the given values:

40 / 100 = Part / 150

Cross multiply:

40 x 150 = 100 x Part, or

6000 = 100 x Part

Now, divide by 100 and get the answer:

Part = 6000 / 100 = <span>60</span>

Yanka [14]
Represent 'a number' by x
7 times x equals 9 more than 4 times x
7 times x=9+4 times x
7x=9+4x
subtract 4x from both sides
3x=9
divide 3
x=3

the number is 3

Mrs lane took a survey of the types of pants her students were wearing. She collected the data of the types of pants her student
kirill [66]
It is always important to go through the given problem first to get a concept of the requiremement. Then all the information's available from the question has to be noted down in such a manner that there would be no need to look at the question while solving.
Total number of students wearing jeans = 10
Total number of students wearing shorts = 9
Total number of students wearing capris = 2
Then the total number of students surveyed by Mrs Lane = (10 + 9 + 2)
                                                                                            = 21
Now percentage of students wearing shorts = (9/21) * 100
                                                                       = (3/7) * 100
                                                                       = 300/7
                                                                       = 42.85 percent
So a total percentage of 42.85% of the students were wearing shorts.
