-4
1.7 because 100 % equals 1 it would always be over 1
Expressed with the equals sign at the end, this sum would be written: 8 - (3 + 2.8) = 2.2
To write 1.95 million in numbers, you would write it as 1,950,000. This is because "million" is equivalent to 1,000,000, so 1.95 million is 1.95 x 1,000,000, which equals 1,950,000.
To write 6100 as a percentage, you would divide 6100 by 100 to get 61. Then, you would multiply 61 by 100 to convert it to a percentage, which equals 6100%. So, 6100 can be written as 6100%.
159x - 297 = 386.7
it equals to 8.10
e=mc^2? e/c^2 = m
