The document is a mathematics worksheet in Portuguese for students. It contains exercises on composing and decomposing numbers. In the first section, students are asked to write out numbers composed of hundreds, tens, and ones such as seven hundreds plus two tens plus five ones. The second section asks students to decompose numbers like forty-six into figures. The third section repeats this with two-digit numbers. The final section has students compose numbers from hundreds, tens and ones such as three hundred plus thirty plus nine. The worksheet aims to practice composing and decomposing numeric values in the hundreds, tens and ones place values.
