- 36% of 175g
\(=36 \div 100 \times 175\)
\(=63\)
\( 2. \frac {4} {9} - \frac {5} {12} \)
Times the left fraction by the right fractions denominator and then visa versa
\( = \frac {48} {108} - \frac {45} {108} \)
- 150L increasedby 43
\(=143 \div 100 \times 150\)
= 214L

- Find the value of \(x\) in the following equations
a) \(3x-5=16\) || (\(-5\))
\(3x=11\) || (\(\div 3\))
\(x= \frac {11} {3}\)
b) \(2x+11=19\) || \(-11\)
\(2x=8\) || \(\div2\)
\(x=4\)c) \(3(x+11)=21\) || Claw methodd) \(4x+3=x+18\) || \(-x\)

Phil buys 4 bags of sweets and eats 15 single sweets.
Jamie has 2 bags of sweets and finds 7 more down the side of the sofa.
If they have the same number of sweets. How many sweets are in the bag
Solve the following question
\(2x+5(3-x)=4(x+6)\)
\(2x+15-5x=4x+24\)
\(-3x+15=4x+24 || +3x\)
\(7x+24=15 ||-24\)
\(7x=-9 ||\div 7\)
\(x + \frac{9} {7}\)
