Question

PLEASE ANSWER WITH SOLUTION PLS

Answer 1

Answer:

whatever% of anything, is just (whatever/100) * anything.

there were a total of 560000 votes, now, off those some are valid and some are invalid.

we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.

how many are the valid ones anyway?  well, 85% of 560000, which is just (85/100) * 560000.

we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?

well, (75/100) * [ (85/100) * 560000 ].

Answer 2

Answer:

See below ↓

Step-by-step explanation:

1.

• Score of the student on examination = marks scored / total marks
• Score = 235/300 [Divide throughout by 5]
• Score = 47/60 [Using long division, approximate to tenths place]
• Score = 0.783 [Multiply with 100 to convert decimals → percentage]
• Score = 78.3%

2.

• Total valid votes = 560 x (100 - 15)%
• Total valid votes = 560 x 0.85
• Total valid votes = 476
• Votes for Magie N. Hawa = 476 x 70%
• Votes for Magie N. Hawa = 333.2 ≅ 333 votes

3.

• 108 girls = (100 - 70)% of pupils
• 108 / 0.3 = number of pupils
• 360 pupils
