# Core 4 Maths — C4.11

**Check, Re-Check and Check Again**

C4.11 has five daily lessons, Monday to Friday. Each retains 32 numbered classroom questions and separate decimal-to-fraction practice. Select C4.11 in the website's level selector, or use the `/level11` entrance.

## What you will practise

Counting and fraction sense covers fraction and decimal sequences, equivalent fractions, fractions of quantities and open-ended fraction comparisons. Decimal place value covers reading a number aloud, complete tenths, digit values, expanded form, rounding and powers of ten. Addition and subtraction includes whole-number calculations and fractions with the requested mixed-number or improper-fraction answers. Multiplication and division covers multiples, operation order and mixed-number calculations.

For the question asking how many **complete tenths** are in a decimal, count complete tenth-sized units in the entire number, not just the digit in the tenths position. The reading question is a Yes/No self-reflection: read the number aloud before recording your response. It is marked reviewed, not verified correct.

## Try your own question first

Enter your own answers and use Check answer or Check answers. A fraction between two values can have many correct answers: the checker tests the stated conditions, not just one particular fraction. Endpoints do not count when the question says strictly between, greater than or less than.

If you need help, open a similar example. Its numbers are different from your question, and its working appears one step at a time. Learn the method, then apply it to your own numbers. The website does not provide a Reveal answer button or your actual question's worked solution.

Use `a/b` for a fraction, `2 1/3` for a mixed number, and brackets for repeating decimals, such as `0.(3)`. Use the answer form requested in the question.
