Webster's method avoids these paradoxes with a mathematical formula that
involves multiplying the fractions by a tiny bit more than 435 and rounding to the nearest whole number.
Explain that students will be writing their own word problems that
involve multiplying a fraction by a whole number.
Not exact matches
All of the problems
involve forming and solving equations, and they also practice: - simultaneous equations - adding and
multiplying fractions - square roots - Pythagoras Full solutions included.
This is a mastery worksheet
involving multiplying and dividing
fractions.
Find the reciprocal of a number given as a

involve:
fractions of amounts, large numbers, money, basic operations (add, subtract,
multiply, divide), order of operations (BIDMAS), factors, multiples, range, odd and even numbers, doubling, greater than, prime numbers, square and cube numbers.
By varying the format and types of numbers
involved (Q5 - 12), students spent much longer thinking about the concepts
involved in
multiplying fractions and less time executing a simple algorithmic process without thinking.
