Yan has already finished 3/5 of the 45 math problems he was assigned today. Each math problem took him 1 4/5 of a minute to comp

kobusy [5.1K]

Answer:

He will finish the rest of the problems in 32.4 minutes.

Step-by-step explanation:

Since we are given that Yan has completed 3/5 of 45 problems i.e.

$\frac{3}{5}*45$

$27$

Thus he has completed 27 problems

Remaining no. of problems are 45-27 = 18

Since he complete each problem in minutes = $1\frac{4}{5} =\frac{9}{5} =1.8$

So, he completes 18 problems in minutes = 18 *1.8 = 32.4 minutes

Hence , He will finish the rest of the problems in 32.4 minutes.

How the heck do you do this?!

Use PEMDAS to figure out the order of operations:

Parentheses
Exponents
Multiplication/Division
Addition/Subtraction

Solve (-4 + -6) first, as this is in parentheses:

$-4 + -6 = -10$

$10 - 5.3 * -10$

Solve 5.3 * -10 next, as this is multiplication:

$5.3 * -10 = -53$

$10 - -53$

Now we can solve the equation:

$10 - -53 = 63$

The answer is 63.
