Answer:
Step-by-step explanation:
The expression is
(1/6+2 2/3)x(1 1/4-1/2)
Looking at the first parenthesis, (1/6 + 2 2/3), 1/6 is a proper fraction while 2 2/3 is a mixed fraction. We would convert 2 2/3 to improper fraction. It becomes 8/3. The first parenthesis becomes (1/6 + 8/3). The LCM is 6 so it becomes
(1 + 16)/6 = 17/6
Looking at the second parenthesis, (1 1/4 - 1/2), 1/2 is a proper fraction while 1 1/4 is a mixed fraction. We would convert 1 1/4 to improper fraction. It becomes 5/4. The second parenthesis becomes (5/4 - 1/2). The LCM is 4 so it becomes
(5 - 2)/4 = 3/4
The expression becomes
17/6 × 3/4 = 17/8 = 2 1/8
A) 186 minutes
b) 3 tyres
We can take 124 and divide it by 4 to see how long it takes him to fit 1 tyre, then use that number to sort the rest out.
124/4 = 31
It takes Liam 31 minutes to fit one tyre to a lorry.
To fit 6 tyres, it takes 6 x 31 = 186 minutes
If he works for 93 minutes,
93/31 = 3 tyres

Answer:
Max made a mistake in step 5.
He should have used division instead of multiplication.
Step-by-step explanation:
In step #5, he made the mistake of multiply 5/6 by 5/6. The reason why this doesn't work is because y is not a full y. When there isn't a number beside a variable, it is implied that it is 1y. To solve for y, you need 1y or else results or inaccurate.
In reality, 5/6 * 5/6 is equal to 25/36. If you divided 5/6 by 5/6, it is equal to 1, which makes y a full y.
