complete the statement
11g=____ mg
1,312.5 is 375% of what number?
The last one I can help you with.
Do you know how to do cross multiplication? I'll set it up for you:
375/100 = 1312.5/x
Then, you would multiply 1312.5 by 100, and divide by 375.
Hope I helped!
To subtract 9 3/10 from 7 14/15, follow these steps:
Step 1: Convert both mixed numbers to improper fractions.
9 3/10 = (9 * 10 + 3)/10 = 93/10
7 14/15 = (7 * 15 + 14)/15 = 119/15
Step 2: Find a common denominator.
The common denominator for 10 and 15 is 30.
Step 3: Rewrite both fractions with the common denominator.
93/10 = (93/10) * (3/3) = 279/30
119/15 = (119/15) * (2/2) = 238/30
Step 4: Subtract the fractions.
(238/30) - (279/30) = (238 - 279)/30 = (-41)/30
Therefore, 9 3/10 - 7 14/15 = -41/30.

To complete the statement "11g = ____ mg", follow these steps:
Step 1: Determine the conversion factor between grams and milligrams.
1 gram (g) = 1000 milligrams (mg)
Step 2: Multiply the given value (11g) by the conversion factor.
11g * 1000mg/g = 11,000mg
Therefore, 11g = 11,000mg.

To find what number is 1,312.5 when it is 375% of that number, follow these steps:
Step 1: Set up the equation.
375% of x = 1,312.5
Step 2: Convert 375% to a decimal.
375% = 375/100 = 3.75
Step 3: Solve for x by dividing both sides of the equation by 3.75.
x = 1,312.5 ÷ 3.75 = 350
Therefore, 1,312.5 is 375% of 350.
To subtract mixed numbers, you can follow these steps:
1. Convert the mixed numbers into improper fractions.
- 9 3/10 can be converted to (9 x 10 + 3)/10 = 93/10.
- 7 14/15 can be converted to (7 x 15 + 14)/15 = 119/15.
2. Find a common denominator.
- The common denominator for 10 and 15 is 30.
3. Rewrite the fractions using the common denominator.
- 93/10 becomes 279/30 by multiplying numerator and denominator by 3.
- 119/15 becomes 238/30 by multiplying numerator and denominator by 2.
4. Subtract the fractions.
- 279/30 - 238/30 = (279 - 238)/30 = 41/30.
5. Simplify the fraction, if necessary.
- 41/30 cannot be simplified further.
- Therefore, the result of subtracting 9 3/10 and 7 14/15 is 41/30.
To complete the statement "11g = ____ mg," we need to convert grams to milligrams. There are 1,000 milligrams in one gram. Therefore, to convert grams to milligrams, we multiply the grams by 1,000.
- 11g will be: 11 x 1,000 = 11,000 mg.
Hence, "11g = 11,000 mg."
To find a number when we know the percentage, we divide the given amount by the percentage fraction (percentage divided by 100).
- To find the number when 1,312.5 is 375% of it, we divide 1,312.5 by 375/100.
- 1,312.5 ÷ (375/100) = 1,312.5 ÷ 3.75 = 350.
Therefore, 1,312.5 is 375% of 350.
