1.45 as a mixednumber in simplestform is 1 9/20.

We have,

To convert the decimal 1.45 to a mixed number in simplest form, we need to express it as a whole number plus a proper fraction.

First, we can observe that the whole number part of the decimal is 1.

To find the fraction part, we look at the decimal portion, which is 0.45.

To convert the decimal portion to a fraction, we place the decimal value over the appropriate place value.

In this case, 0.45 is equivalent to 45/100.

Next, we simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 5 in this case:

45/100 = (45 ÷ 5) / (100 ÷ 5) = 9/20

Now, we can express the decimal 1.45 as a mixed number:

1.45 = 1 + 9/20

Lou spends the total amount would be $26.98 on​ gas which is determined by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

The following information is provided in the problem :

Lou topped up the tank with $3.80 per gallon of petrol.

Lou's car's 13-gallon tank held 5.9 gallons.

If he filled the tank, you can determine the total amount of money Lou spent by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.

So the total amount would be:

⇒ (13 - 5.9)(3.80)

⇒ (7.1)(3.80)

⇒ 26.98.

Therefore, the total amount would be $26.98
