How about 5 x 9 x enough multiples of 10 to give you 5 digits? 5 x 9 = 45 5 x 9 x 10 = 450 5 x 9 x 10 x 10 = 4500 5 x 9 x 10 x 10 x 10 = 45000 18225
87.59 = (8 x 10) + (7 x 1) . (5/10) + (9/100)
They are in the same ratio 2:9 multiplied by 5 makes 2 x 5 = 10 9 x 5 = 45 so is 10:45
area of rectangle = base x height = 9 x 10 = 90 square cms
5/7 x 9/10 = 9/14
How about 5 x 9 x enough multiples of 10 to give you 5 digits? 5 x 9 = 45 5 x 9 x 10 = 450 5 x 9 x 10 x 10 = 4500 5 x 9 x 10 x 10 x 10 = 45000 18225
You mean "What percentage is 90 million of 5 billion?" If so, [(90 x 10^6) x 100] / (5 x 10^9) = (9 x 10^9) / (5 x 10^9) = 9/5 = 1.8%
10 x 9 = 90 square feet
(-9)*(-5) + (-10) = 45 - 10 = 35
59=(5 X 10) +(9 X 1)
0.0000009 in Scientific Notation = 9 x 10-7
87.59 = (8 x 10) + (7 x 1) . (5/10) + (9/100)
2/5 x 2/2 = 4/10 1/2 x 5/5 = 5/10 4/10 + 5/10 = 9/10 9 tenths
They are in the same ratio 2:9 multiplied by 5 makes 2 x 5 = 10 9 x 5 = 45 so is 10:45
area of rectangle = base x height = 9 x 10 = 90 square cms
5/7 x 9/10 = 9/14
950.95 = (9 x 100) + (5 x 10) + (0 x 1) + (9/10) + (5/100)
