Ratios are numerical way/method used to compare two quantities of the same type, the quantities can be weight, money, ages, marks, length, volume, Area etc.When two quantities are being compared, they can be in fraction or separated by column in-between them, example x/y or x:y respectively. If a/b and x/y are two different ratios given,
Before one can add or subtract in standard form, the powers of the 10( that is ⁿ) in the numbers to be added or subtracted must be made to be equal. Example 1: 5.4 x 10⁴ + 6.04 x 10³ Solution:Either you make the first power to be equal to the second power or you

A particular number is said or observed to be in standard form if it is written in this form:V x 10ⁿ. 1 ≤ V < 10Where V can be in positive/negative whole number or positive/negative decimal number. (ⁿ) is the number of times a point moves either on the LEFT hand side or at the
Approximations are estimate in Amount, Numbers, Distances etc. that are almost correct, but not exact. It is a unique method of counting to nearest wholes, which might be Tens, Hundreds, Thousands, Weights, Distances, Time and so many other values. Example 1: Correct 4726.6282 to the nearest(a) thousand, (b) hundred, (c) ten (d) whole number, (e)
Significant figures (s.f) is the positioning of digits from 0 to 9 in a numeral with the exclusion of zero in some cases, this is applicable to both Whole and Decimal numbers. Characteristics of significant Figures Any non Zero digit is significant, eg. Digits from 1 to 9. That is 1 2 3 4 5

FRACTIONS: fractions are wholes that consist of Numerators and Denominators that are separated with a Division sign. Numerator: (At the top) Division sign: (At the middle) and Denominator: (At the bottom). It is simply a figure placed on another figure. Example of a fraction is 1/x, Where 1 is the Numerator (/) is the
ADDITION AND SUBTRACTION IN NUMBER BASES. Most students have been finding it so difficult to add or subtract in number bases. The method used on tackling the problems is not different from what we have done here. Example 1: (Number Bases) If you are given 264, 86, 475 all in base nine to be
Practice converting fractions to decimals: To convert Fractions of Decimal Numbers in base ten to base two, the given fraction needs to be split into smaller fractions in such a way that when added will still give you back your original fraction, and all the numerators of the new fractions formed must be factors of
