Answer: The total point is 70

Step-by-step explanation:

Let x represent the total point of the test

90% of x = 63

90/100 × x =63

90x / 100 = 63

cross multiply

90x = 6300

Divde bothside by 90

90x / 90 = 6300/90

x = 70

Therefore the total possible mark is 70

4736 divided by 100 for math
damaskus [11]
If you divided 4.736 ÷ 100 you have to find the times 100 is in 473, is 4 times, then you have to find how many times is 100 in 736, is 7 times, then you have 36 but this is not a entire number then you add a 0, 100 is 3 times in 360, now you have a 6, you add two zeros, 100 is six times in 600. 47,36 is the answer.
