BASIC LABORATORY MATHEMATICS
→ MULTIPLICATION is indicated by:
axb a•b a(b) (a)(b)
→ DIVISION is indicated by:
a b a a/b
b
→ FRACTIONS indicate a part of a whole.
The numerator is the number written above the line of a fraction.
The denominator is the number written below the line of a fraction.
The line between the numerator and the denominator indicates division. The numerator is
divided by the denominator.
Example: 7 7 is the numerator; 16 is the denominator.
16
This fraction means 7 is divided by 16.
→ DECIMALS are determined by carrying out the division of a fraction.
Example: 7 = .4375
16
A decimal can be converted to a fraction with a denominator of 10 or some power of 10.
Ten Thousandths
Hundredths
Thousands
Tenths
0.2315
This decimal can be converted to the fraction 2,315
10,000
→ ADDITION WITH DECIMALS
To add decimals, set the decimals in a vertical column. Add as for whole numbers, placing the
decimal point in the answer below the column of decimal points.
Example: 37.12 + 4.495 + 7.0 + .0013
37.12
4.495
7.0
.0013
