Given: Write .01 as a percent. The number n = 0.01. This number represents a rate. To change a rate to a percent: n 100 %. .01 100 =.0001 %. Answer link. PJ. Jul 17, 2018. To convert a decimal number to a percentage, multiply by 100 1 % so 0.01 = 1 %.
Explanation: 0.01 is a decimal fraction and hence as it is only up to 2 places of decimal, it is equivalent to. 0.01 = 0 10 + 1 100 = 1 100. Hence in fractions, 0.01 is 1 100. To convert a fraction into percent, one should multiply it by 100. Hence 0.01 = 1 100 = 1 100 × 100% = 1%. 0.01=1/100=1% 0.01 is a decimal fraction and hence as it is ...
Answer link. You can reuse this answer. 1 Let's write this in maths first: 10 div (1 div 0.1) 10 div 1/0.1 We can treat this as a fraction calculation or as a decimal calculation. As a fraction: To divide, multiply by the reciprocal: 10 xx 0.1/1 = 1 As a decimal, change the denominator into 1 10 div (1xx10)/ (0.1 xx10) =10 div 10/1 =10 div 10 = 1.
For 0.2, the tenths place, 2, is divided by 10: 2 10, which reduces to 1 5 (alternatively, 0.2 ⋅ 10 10 = 2 10 = 1 5). To convert from fractions to decimals, use division. For 1 5, divide 1 by 5 (demonstrating long division is kind of difficult on Socratic, however) which equals 0.2. (Other examples: 3 7 = 0.4286, 9 8 = 1.125) Answer link.
Given: 0.4 ÷ 0.008. Write as 0.4 0.008. 0.4 ×1000 0.008 × 1000 = 400 8. Lets split (partition) the number to make it easier to work out in our heads. 400 can be slit (partitioned) into 10× 40. So we can rewrite 400 8 as. 10 × 40 8. But 5 ×8 = 40 that is: 40 ÷ 8 = 5 so we end up with. 10× 5 = 50.
0.005g ⋅ 103 mg 1g = 5 mg. Since this represents the number of milligrams of solute present for every 1 mL of the solution, you can say that the solution has a concentration of. concentration = 5 mg mL−1 −−−−−−−−−−. The answer is rounded to one significant figure. Answer link. "5 mg mL"^ (-1) The solution's mass by ...
How do you write numerical values of expressions written in scientific notation? If the power is positive, move the decimal point to the right, but if the power is negative, then move the decimal point to the left. Let us look at the following examples. Examples. #1.2345 times 10^3=1234.5#. #1.2345 times 10^7=12345000#.
Explanation: You can divide INTO a decimal, but not BY a decimal. So we need to change 0.04 into a whole number. 9.2 0.04 × 100 100 = 920 4 100 100 = 1. Now we can divide as usual to get 230. 230 You can divide INTO a decimal, but not BY a decimal.
When dividing by a fraction turn it upside down (invert it) and then multiply instead. So 50000 ÷ 0.001 gives the same answer as 50000 × 1000 1. Just put the 5 first, count the zeros and write that count of zeros after the 5. 5 with 4+3 zeros → 50000000. Some people like to put a comer between each of 3 zeros reading right to left.
Changing fractions to a decimal you just have to divide the Quotient by the Divisor. For example; 2 5 → Fraction. Now dividing 2 by 5; 2 ÷ 5 = 0.4 → Decimal. Changing fractions to a percentage, you just have to multiply the fraction by 100. For example; 2 5 → Fraction. 100% → Percentage.
