Step-by-step solution for: GRADE 6 TERM 4 MATHEMATICS WORKSHEET 1 • Teacha!
Here are the step-by-step solutions for the math problems on the page.
*Multiply the numbers.*
69. $1\,866 \times 11$
* $1\,866 \times 10 = 18\,660$
* $1\,866 \times 1 = 1\,866$
* $18\,660 + 1\,866 = 20\,526$
70. $486 \times 30$
* Ignore the zero first: $486 \times 3$.
* $400 \times 3 = 1\,200$, $80 \times 3 = 240$, $6 \times 3 = 18$.
* $1\,200 + 240 + 18 = 1\,458$.
* Add the zero back: $14\,580$.
71. $1\,165 \times 5$
* $1\,000 \times 5 = 5\,000$
* $100 \times 5 = 500$
* $60 \times 5 = 300$
* $5 \times 5 = 25$
* Total: $5\,000 + 500 + 300 + 25 = 5\,825$.
72. $1\,141 \times 9$
* $1\,141 \times 10 = 11\,410$
* Subtract one group of $1\,141$: $11\,410 - 1\,141 = 10\,269$.
73. $1\,466 \times 50$
* Multiply by 5 first: $1\,466 \times 5 = 7\,330$.
* Add a zero: $73\,300$.
74. $2\,382 \times 50$
* Multiply by 5 first: $2\,382 \times 5 = 11\,910$.
* Add a zero: $119\,100$.
75. $1\,600 \times 9$
* $16 \times 9 = 144$.
* Add the two zeros: $14\,400$.
76. $221 \times 10$
* Just add a zero to the end: $2\,210$.
77. $3\,807 \times 4$
* $3\,000 \times 4 = 12\,000$
* $800 \times 4 = 3\,200$
* $7 \times 4 = 28$
* Total: $12\,000 + 3\,200 + 28 = 15\,228$.
78. $818 \times 25$
* Think of this as multiplying by 100 and dividing by 4 ($25$ is one-quarter of $100$).
* $818 \times 100 = 81\,800$.
* Half of $81\,800$ is $40\,900$.
* Half of $40\,900$ is $20\,450$.

*Solve the fraction problems.*
79. $7 \frac{1}{2} - 1 \frac{1}{2}$
* Whole numbers: $7 - 1 = 6$.
* Fractions: $\frac{1}{2} - \frac{1}{2} = 0$.
* Answer: 6
80. $7 \frac{17}{20} - 5 \frac{18}{20}$
* You cannot subtract $\frac{18}{20}$ from $\frac{17}{20}$. Borrow 1 from the 7.
* $7 \frac{17}{20}$ becomes $6 \frac{37}{20}$ (because $1 + \frac{17}{20} = \frac{37}{20}$).
* Whole numbers: $6 - 5 = 1$.
* Fractions: $\frac{37}{20} - \frac{18}{20} = \frac{19}{20}$.
* Answer: $1 \frac{19}{20}$
81. $8 \frac{1}{11} - 2 \frac{3}{11}$
* Borrow 1 from the 8.
* $8 \frac{1}{11}$ becomes $7 \frac{12}{11}$.

* Fractions: $\frac{16}{9} - \frac{8}{9} = \frac{8}{9}$.
* Answer: $2 \frac{8}{9}$
83. $3 \frac{13}{16} + 2 \frac{9}{16}$
* Whole numbers: $3 + 2 = 5$.
* Fractions: $\frac{13}{16} + \frac{9}{16} = \frac{22}{16}$.
* Simplify fraction: $\frac{22}{16} = 1 \frac{6}{16} = 1 \frac{3}{8}$.
* Add to whole number: $5 + 1 \frac{3}{8} = 6 \frac{3}{8}$.
* Answer: $6 \frac{3}{8}$
84. $8 \frac{2}{17} - 5 \frac{5}{17}$
* Borrow 1 from the 8.
* $8 \frac{2}{17}$ becomes $7 \frac{19}{17}$.

* Whole numbers: $8 - 6 = 2$.
* Fractions: $\frac{142}{75} - \frac{68}{75} = \frac{74}{75}$.
* Answer: $2 \frac{74}{75}$
