To solve this expression, you need to follow the order of operations (PEMDAS/BODMAS), which states that calculations should be done in the following order: parentheses/brackets, exponents/orders, multiplication/division, and addition/subtraction.
Using this order of operations, the expression 2/5 × 37.5 - 7 is:
First, perform the multiplication:
2/5 × 37.5 = 0.4 × 37.5 = 15
Now, substitute the result back into the expression:
15 - 7
Finally, subtract 7 from 15:
15 - 7 = 8
Therefore, the value of the expression 2/5 × 37.5 - 7 is 8.
2/5×37.5-7
